FIELD AND BACKGROUND OF THE INVENTION

This invention relates to a telecommunications call augmentation system and in particular to a method of and apparatus for augmenting a call with media content. The invention has particular relevance to providing a user of a telephone, especially of a mobile telephone or cellphone, such as a smartphone, with targeted media content in a noticeable yet unobtrusive fashion. Various embodiments are described wherein an initial item of media content is used as a trigger or advertisement which when activated by the user presents further media content.

Modern telephones have become increasingly sophisticated and many are able to present or play a wide variety of forms of media content to their users. This is especially the case with those mobile telephones or cellphones known as ‘smartphones’, which are effectively portable computers with telephone functionality and often internet connectivity.

Various attempts have been made to make use of this media playing ability of smartphones in order to present the user with pertinent information—for example, service alerts and advertisements—at times other than those at which the user is specifically seeking them out. A particular challenge is to make such alerts noticeable to the user yet not overtly obtrusive. The present invention aims to address at least some of these problems.

SUMMARY OF THE INVENTION

Generally, there is provided a method of augmenting a telecommunications call with media content, preferably the media content being dependent on an attribute of the called or calling party, more preferably the media content enabling the called or calling party to access further related media content or services.

According to an aspect of the invention there is provided a method of augmenting a telecommunications call, the method comprising: detecting a telecommunications call event at a user telecommunications device; selecting an item of media content, the item of media content being associated with the calling party; augmenting the call with the item of media content; detecting a user interaction with the device in response to the item of media content; and optionally transmitting information relating to the user interaction to the calling party.

Preferably, the item of media content may be retrieved from a local cache on the device. The item of media content may have previously been provided by the calling party to the local cache on the device. The media content may have previously been retrieved or downloaded from a remote server, for example by an application on the user device. The application may be provided by or otherwise associated with the calling party. The downloading of the item of media content may be integrated with an update of the application. The application may periodically download media content items for use in augmenting telecommunications calls.

Alternatively, or in addition, the downloading of the item of media content may occur in response to a user interaction with the calling party. The downloading of the item of media content may be dependent on the user granting permission via interacting with an item of media content present on the device.

Alternatively, or in addition, the device may be prompted by the telecommunications call event to download the item of media content from the remote server via a signal received from a remote server and/or by the telecommunications call event.

Preferably, the item of media content may be associated with a user profile, where the profile may be dependent on one or more of: network operator/tariff, device model, other applications on device, call/text frequency, data usage, volume of changes of location, battery size, and number of contacts.

Preferably, the item of media content may be associated with an expiry date and/or time beyond which it is no longer presented to the user.

In some embodiments, the media content is provided as a payload part of the telecommunications call. Alternatively, or in addition, the media content may be provided via a different communications channel than that used for the provision of the telecommunications call. For example, the telecommunications call may be provided via a voice channel, the media content via a data channel. The item of media content may be downloaded via a higher speed channel or network than that used for the telecommunications call.

The method may further comprise receiving at the user device a signal enquiring about the presence of items of media content, preferably a specific media content item, in the local cache. The method may then further comprise the device signalling that items of media content have, preferably that the specific item of media content has, been downloaded to the device cache and/or that the items are or item is available for use in augmenting the telecommunications call. If a specific item of media content is not available, another, preferably related, item of media content may be selected from the device cache with which to augment the telecommunications call.

Preferably, the method may further comprise prioritising the presentation of the item of media content to the user ahead of other media items. The prioritising may be based on a list of qualifying contact details, preferably provided to and/or stored on the user device. The method may further comprise prioritising the handling of an incoming telecommunications call by an application on the user device which supports the method of telecommunications call augmentation. The prioritising between applications may be in dependence on the time of last use of the applications.

Preferably, the item of media content may be presented on the incoming call screen. The item of media content may present the user with an indicator or identifier allowing the user to identify the calling party. The indicator may be a trade mark.

The item of media content may comprise at least one of: audio, preferably in the form of a ringtone, and/or a visual item, preferably text or an image.

The item of media content may indicate planned call subject, topic or content. Alternatively, or in addition, the item of media content may indicate information relating to a user account, order or event, preferably one with the calling party.

The item of media content may be selected from a plurality of available items relating to the calling party. The selection may be based on time, user or device location, user characteristics, and/or previous user interactions. The item of media content may be selected in dependence on a schedule, preferably downloaded to the user device. The order of items in the schedule may be changed remotely, preferably by means of a signal received by the user device.

The item of media content may present the user with a menu of options; preferably, the menu of options comprises at least two items.

The user interaction may comprise a touch, such as a press or a swipe (for example of a media image, such as a button, displayed on the screen of the device), by voice or other bodily movement, optionally the method may further comprise displaying a message to the user in dependence on the interaction.

The information transmitted relating to the user interaction may comprise one or more of: a selection from the menu of options, navigation of an IVR system, the expression of an interest, mood, a preference, a vote or an instruction. A further item of media content may be presented to the user in response to the user interaction. Optionally, a further user interaction may be detected and information relating to the further user interaction may be preferably transmitted to the calling party.

The instruction may comprise the user scheduling or re-scheduling an event, for example via a selection from a menu of alternative dates and/or times, interacting with a media content item representation of a clock and/or calendar, or swiping of a slider. The instruction may comprise selecting an amount, for example via a selecting from a menu of alternative amounts, or swiping of a slider. The instruction may comprise a request such as for a postponement (say specifying a delay for a later call-back), the use of or switch to an alternative means of communication (for example, text chat rather than voice call), or that the calling party desist. The instruction may further comprise scheduling the user device to initiate contact with the calling party at a future time. The user may, for example, be presented with a related item of media content ahead of the contact with the calling party being initiated.

Electronic files may be transmitted between the user and the calling party.

Preferably, the method may further comprise reporting to the calling party whether the telecommunications call was augmented with the item of media content, more preferably determining and reporting to the calling party whether the user's behaviour was altered in response to the item of media content.

The calling party may comprise a second user with a second user device. One or other user may select from a plurality of options, preferably information regarding the selection or option selected being transmitted to the other user, and/or edit the items of media content used to augment the telecommunications call to the other user.

Preferably, the calling party may provide information, such as an indication of the subject of the call, by way of text or an image (for example an emoticon), ahead of the call. The calling party may communicate a message, for example as a notification, say a push notification, in parallel with placing a call, preferably relating to the reason for calling

Alternatively, or in addition, one or other user may select from a plurality of options and/or edit the actions resulting from interaction of the other user with the item of media content used to augment the call.

Alternatively, or in addition, the telecommunications call may be augmented with an item of media content mid-call.

The user may receive a request from the calling party to consider, and preferably to interact with, an item of media content augmenting the telecommunications call.

The item of media content may be one or more of: an image or video for tutorial purposes, a secure password, a live video or text feed. The item of media content may present the user with the option to share content on social media, open a chat window, or complete a survey.

Alternatively, or in addition, the item of media content may be presented to the user on a call waiting screen, when the user is already engaged on a telecommunications call with another party.

On termination of the call, an action may be performed in dependence on a uniform resource identifier or URI associated with the item of media content.

Information relating to the user interaction may also or alternatively be transmitted to a party other than the calling party.

According to another aspect of the invention there is provided a method of augmenting a telecommunications call placed to a user telecommunications device, the method comprising: selecting an item of media content, the item of media content being associated with the calling party; augmenting the call with the item of media content; and determining and reporting to the calling party whether the user's behaviour was altered in response to the item of media content.

According to another aspect of the invention there is provided apparatus for augmenting a telecommunications call, comprising: a detecting module for detecting a telecommunications call event at a user telecommunications device; a selecting module for selecting an item of media content, the item of media content being associated with the calling party; an augmenting module for augmenting the call with the item of media content; a module for detecting a user interaction with the device in response to the item of media content; and a module for transmitting information relating to the user interaction to the calling party.

According to another aspect of the invention there is provided a system for augmenting a telecommunications call, the system comprising: a media server, for storing items of media content; a calling device, for placing telecommunications calls to a client or user device; optionally, a client or user device; wherein the system is adapted to carry out any method as described.

According to another aspect of the invention there is provided a method of augmenting a telecommunications call, the method comprising: detecting a telecommunications call event at a user telecommunications device; selecting an item of media content, the item of media content being associated with the calling party; augmenting the call with the item of media content; the item of media content previously having been provided by the calling party to a local cache on the device. Preferably, the item of media content is downloaded to the user device via an application on the user device. The application may be provided by or otherwise associated with the calling party.

Generally, the invention provides for a user of a telecommunications device to be primed for a telecommunications call via the initial provision of information by—or preferably the exchange of information with—the calling party before the call is answered.

In some embodiments, there is provided (incoming call) screen communications to allow customers or users to communicate their preferences to calling parties with the touch of a button, preferably via or prompted by the media content item. This could be call back preferences or smartphone preferences.

With the advent of this technology ‘Smart Warm Calling’ will change the communication dynamic between service providers and their customers.

According to another aspect of the invention, there is provided a method of augmenting a telecommunications call, the method comprising: detecting a telecommunications call event at a user telecommunications device; selecting an item of media content, the item of media content being associated with a uniform resource identifier or URI; augmenting the call with the item of media content; detecting a user interaction with the item of media content; and on termination of the call, performing an action in dependence on the resource identified by the URI.

Augmenting the call in this way may allow for a selected media content item to be presented to a user of a telecommunications device in a noticeable yet unobtrusive fashion (and without distracting the user while the call is in progress). This may be particularly useful for presenting public notices and alerts, including advertising.

Preferably, the selection of the item of media content is in dependence on an attribute of the call. The selection of the item of media content may be in dependence on an attribute of the user device and/or an attribute of the user, such as the user's browsing history, call history, and text message data, an associated identity, an associated location and/or an associated date and/or time.

Preferably, the selection of the item of media content is in dependence on an attribute of a party placing the call.

Preferably, the selection of the item of media content is in dependence on an attribute of a party receiving the call.

Preferably, the item of media content comprises an image or video, and augmenting the call comprises displaying the media content to the user, preferably overlaid on a call screen of the device.

Preferably, the item of media content comprises audio, and augmenting the call comprises playing the media content to the user.

Preferably, the method further comprises receiving the item of media content from a remote server. Receiving the item of media content may occur before an incoming call is received or an outgoing call is made; presentation of the media content to the user may occur before, during or after the incoming call is received or the outgoing call is made.

Thus, in one example, the media content is presented to the user during call initiation or set up, that is, at the time of an incoming call alert, or while the user is waiting for a placed outgoing call to be picked up. In a further example, the media content is presented to the user after termination of a call (incoming or outgoing). Furthermore, the media content might be presented to the user multiple times during the placement or reception of a call and/or the media content might be split up so that, for example, part of the media content is presented while a call is being initiated, and a further portion of the media content is presented after termination of the call.

Preferably, the selection of the item of media content is performed at a remote server.

Preferably, the method further comprises storing the item of media content in a local cache on the user device. This may reduce the time required for the media content to be first displayed by the device.

This and other aspects of the invention may also comprise one or more of the following:

The item of media content may be stored in the address book or contacts application or other database on the user device. This may allow implementation of the invention in restrictive operating systems, for example where direct control by third parties of the incoming call screen is not otherwise permitted.

The item of media content may be a contact profile or image, potentially applied to an existing contact for which no image is present. This may be pre-loaded in advance of the call or in some embodiments the information may be provided and the contacts updated in real-time.

The item of media content may comprise an operating system or app notification, preferably an interactive notification allowing the user to respond before, during or after—or instead of—taking the incoming call. The user response may be via a messaging system, such as SMS.

The item of media content may be a combination of a notification, preferably a push notification, and a media item or contact information stored locally on the device. Preferably, the notification is synced with the incoming call. Embodiments may make use of phone or device internal diagnostics and/or the network signal, preferably to mitigate for signal and/or hardware delays.

The app and/or user device may be configured to report to the calling or third party that it is in a good signal reception area and has app notifications activated. Alternatively, this information may be obtained in response to the device being polled by the calling or third party in advance of a potential call.

Preferably, a determination is made as to whether the device user is likely to be poised to receive a call. This determination may be made according to data obtained from native device hardware technologies—such as the smartphone accelerator, eyeball trackers and/or camera(s). Alternatively, or in addition, contextual information regarding user behaviour may be used.

Preferably, the user may set preferred times for when they would be willing to accept a call or excluded times when they would not be so willing.

Preferably, a determination is made whether and when to place a call to the user in dependence on one or more of: signal strength at the device, configuration of the device, amenability of the user and user preference.

Preferably, a determination is made as to whether the user has seen and their reaction to—and optionally determine whether they benefited from—the call.

Preferably, a user incentive scheme is used, such as detected interaction with the item of media content earning the user points or prizes.

The call (event) may be an incoming or an outgoing call.

Preferably, the user interaction with the item of media content is reported to a remote server.

Preferably, items of media content are provided to the remote server by a media content provider.

The present invention relates to providing advertising space on the incoming call screen of a mobile phone.

Generally, there is provided a method of augmenting a telecommunications call with media content on an incoming or outgoing call screen of a mobile phone.

Embodiments of the present invention may comprise one or more of the following features:

-   -   1. a method of persuading mobile phone users to accept call         screen advertising, in particular in the form of a hyperlinked         incoming call screen advertisement     -   2. a method of displaying a media content item associated with a         telephone call in a way that does not interrupt the call,         preferably making use of screen “real-estate” which is otherwise         underused     -   3. a method for accessing a user's incoming call screen for         displaying media content, for example advertisements     -   4. a method of providing user-friendly call screen         advertisements which can be linked to relevant information     -   5. a method of co-ordinating multiple instances of call         augmentation applications, preferably apportioning advertising         income appropriately (for example according to user interactions         with particular application instances)     -   6. enabling software developers to bundle software for providing         such call screen advertising together with their (“free”)         software applications in addition to—or instead of—facilitating         advertising within their software applications, and preferably         enabling users to select which form of advertising they would         prefer.

The item of media content may be an advertisement selling at least one product, promoting or providing information, or displaying any other type of information for informing the user.

Generally, in accordance with one broad aspect of the invention there is provided a method of providing a media content item such as an advertisement to a user of a mobile device, the mobile device comprising at least a phone function and a screen, the method comprising: providing a call screen display software application to the phone of a user, wherein said application comprises means for displaying media content on at least the incoming call screen of said mobile device; selecting at least one media content item such as an advertisement to be displayed on said call screen; providing said media content item such as an advertisement to said phone; and displaying said media content item such as an advertisement on said call screen, preferably when a call occurs between said user and a second party.

The second party may be the calling party.

A potential advantage of the present invention is that it may provide a further opportunity for third parties such as advertisers; that of the incoming call screen. A further potential advantage is that it may provide a means of gaining access to the user's call screen via a second software application. A still further potential advantage is afforded by a delay feature which enables hyperlinks within the media content items or advertisements to be clicked without interrupting a call.

In this document, the user—or first party—refers to the user of the smartphone or other communications device.

The second party is the party involved in the conversation with the user. This may be a person such as an acquaintance, who may be the caller or callee, or may be an automated call handling system, answerphone, or any other party partaking in a call.

Preferably, the media content item provides information from a third party other than the second party, that is, the third party is neither the user nor the second party involved in the call. The third party may, for example, be a vendor advertising their products, or an authority providing public information such as news or weather. The third party may alternatively be the provider of the communications network used by the smartphone or other communications device.

The media content item may be an entire page, a banner, and may cover all or any part of the mobile device screen. Preferably the media content item covers most of the screen, but leaves uncovered the area of the screen in which the operating system of the mobile device displays the caller ID.

The media content item may comprise at least one hyperlink which links to a phone number of the third party. This hyperlink may delay calling the phone number of the advertiser until the end of the current phone call, and automatically call the phone number at the end of the current call, or may display the number to be dialled along with an option to dial it, when clicked and for the duration of the original call, or only at the end of the original call. Alternatively, the hyperlink may connect to a web site or page.

References to media content item, image and coding are used interchangeably.

The call-screen display software application may be a software component installed on the mobile device, wherein said application comprises means for displaying media content on at least the incoming call screen of said mobile device.

The media content able to be displayed may be a wide variety of media content such as pictures, videos, internet data and the like.

Generally, the term uniform resource identifier or URI refers to any means, such as a network or web address (eg. a URL) or number (eg. an IP address), by which a resource, such as an item of media content, may be located and/or identified. With reference to a client device, a URI may direct to a location internal to the client device (eg. to a local cache) or to an external location, such as a server accessible over a network.

Software applications, especially in the context of mobile phones or smartphones, may also be referred to herein as “apps”.

Preferably, the method when implemented as a mobile phone application or ‘app’ conforms to the guidelines or policies of the network/operating system provider or app distributer, for example, by conforming to requirements such as:

-   -   making clear to the user the association of the app with the         media content     -   not impermissibly changing device function without user consent     -   if changes are made, making clear to the user which changes are         due to the app     -   allowing the user to easily reverse any changes via device         and/or app preferences—or by uninstalling the app     -   not simulating system notifications or warnings     -   allowing the user to dismiss media content presented by the app     -   not interfering with third party media content

The software application may be used to display an item of media content on the call screen of a mobile device when a call occurs between the mobile device user and a second party. The call screen is defined as the image or content displayed on the screen when a call occurs. This may be for the duration of the call, part of the call, or only until the call is answered. The call screen usually displays information about the second party in the call, such as a phone number or name, along with means for interacting with the call by answering, rejecting, putting on hold, and the like. The call is preferably an incoming call although it may additionally or alternatively be an outgoing call.

The system also provides for various ways of charging for the media content, for example on a CPM (cost per mille or thousand) impressions basis, or CPC (cost per click), or a combination of both.

Further features of the invention are characterised by the appended claims.

The invention also provides a computer program and a computer program product for carrying out any of the methods described herein, and/or for embodying any of the apparatus features described herein, and a computer readable medium having stored thereon a program for carrying out any of the methods described herein and/or for embodying any of the apparatus features described herein.

The invention also provides a signal embodying a computer program for carrying out any of the methods described herein, and/or for embodying any of the apparatus features described herein, a method of transmitting such a signal, and a computer product having an operating system which supports a computer program for carrying out the methods described herein and/or for embodying any of the apparatus features described herein.

The invention extends to methods and/or apparatus substantially as herein described with reference to the accompanying drawings.

Any feature in one aspect of the invention may be applied to other aspects of the invention, in any appropriate combination. In particular, method aspects may be applied apparatus aspects, and vice versa. As used herein, means plus function features may be expressed alternatively in terms of their corresponding structure, such as a suitably programmed processor and associated memory.

Furthermore, features implemented in hardware may generally be implemented in software, and vice versa. Any reference to software and hardware features herein should be construed accordingly.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

FIGS. 1 and 2 show an overview of a telephone call augmentation system 1. A client device 10, comprising for example a telephone handset—such as a smartphone—is adapted to receive telephone calls from a second client device, telephone 15, over a communications network 20.

Network 20 may be an IP-based network, a 3G (or higher) telecommunications network or represent a combination of different types of communications networks.

Telephone 10 is also in communication via network 20 with a media server 30, which stores (for example in a database) and serves media content from local storage 32 and/or remote storage 34 to telephone 10, which may optionally store the received media content locally at store or cache 112 (which may be internal to telephone 10) for later display.

FIGS. 3 and 4 show the telephone handset 10 in more detail, including the display screen 106 on which callerID information 104 identifying the caller is usually displayed when the telephone 10 receives an incoming call. Also shown are example contents of the system memory or software architecture 70 of the telephone 10 when in operation, showing the operating system (OS) 72, the “dialler” application 114 which handles the making and receiving of telephone calls, and telephone call augmentation application (commonly referred to as an “app”) 100. Local storage 112 may be shared by the operating system 72 and software applications installed on the telephone 10.

In brief, when the app 100 is active and telephone 10 receives an incoming call, a media content image 101 is shown on the screen 106 overlaid on top of the default incoming call screen 104 (or, in the case of audio media content, played from the loudspeaker in place of the ringtone).

The user can then optionally select the media content image 101 (which will cause it to be shown after the current call has ended) and can also elect whether to accept or decline the call as normal.

The media content is displayed on the incoming call screen rather than within the app itself, i.e. the display of media content image 101 is integrated with the usual display of information on screen 104.

A software development kit may also be provided to allow third parties to develop variants of the telephone call augmentation application “app” 100, which is then optionally bundled with their own “host” apps.

In some embodiments, the software system—also referred to here as “Incall”—in its full form comprises three components:

-   -   A mobile SDK which displays advertisements on the incoming call         screen of mobile devices     -   An automated brokerage system which connects developers with         advertisers, provides advertising analytics and handles payment         flows and business logic     -   A series of algorithms that determine which advertisement(s)         should be displayed on the device.

A basic commercial embodiment may comprise the following:

-   -   A mobile SDK which bundles the code to display the         advertisements so that it can be bundled into third-party apps     -   A web interface front-end which facilitates the manual         administration of the advertising system, and which provides a         basic set of metrics from which financial data can be calculated     -   A web back-end and protocol which handles the storage of         adverts, the transmission of adverts to the clients

Detailed Overview

Generally, the system 1 comprises the following components:

-   -   A client or user device, typically a smartphone 10     -   A server 30 which manages and tracks the media content 108,         determines which items of media content are to be sent to the         user device 10, and delivers the media content 108 to the         application 100.     -   Media content     -   A client software application 100 to serve media content to a         smartphone     -   A background service     -   An algorithm (optionally, two algorithms, one on the server 30         and/or one as part of the client app 100) to select the         appropriate media content 108 with which to augment the call     -   Optionally, a SDK (software development kit) for the development         of third-party variants of app 100, particularly for mobile         devices

The software application may be pre-installed on the mobile device, or may be available to download for free or for a price from the internet and/or from a software application platform such as iTunes™ or Android Market/Google Play and/or bundled with or otherwise coupled with other (potentially free) apps.

Client Device

The mobile or client device comprises at least a screen 106 and a phone function in the form of a dialler circuit or application 114, which handles incoming and outgoing calls and displays an incoming call screen image including a caller ID on the screen of the device, among other functions.

The screen may be an LCD screen, touch screen, or the like. Preferably the mobile device further comprises internet connection capability and an internet browser. Such devices are commonly referred to as ‘smart phones’.

Server

The server may send items of media content to local caches upon receipt of media content requests, or may push them to the caches periodically, or when new media content becomes available.

The items of media content may alternatively be sent from the server(s) directly to the application directly using, for example, a cloud-based service such as Google Cloud Messaging (for Android) or Push Notifications (for iOS).

The server 30 applies a proprietary algorithm to determine the media content 108 to be displayed. The server 30 also establishes an audit trail and maintains accounts for each app 100 and media content 108 selections in order to distribute revenues to developers.

The server may perform any or all of the following back-end activities:

-   -   maintaining a global database of all the items of media content;     -   applying an algorithm to determine which items of media content         should be delivered to the client-side app and/or to the cache         on the mobile device of the user;     -   maintaining an audit trail comprising records of which items of         media content have been displayed (served) and which hyperlinks         have been selected (clicked);     -   receiving payments from media content providers, calculating         revenue share, and making payments to developers, such as second         software application developers.

The server may also perform any or all of the following front-end services:

-   -   secure area for media content providers to manage their items of         media content and make payments;     -   secure area for software developers to register their software         application (for example, by means of identifiers) and receive         payment;     -   secure area for system administrators to monitor the overall         system status and retrieve media content provider/developer         records.

The server may be implemented for example on the LAMP (Linux, Apache, MySQL, PHP) stack as a PHP application with a MySQL database for storing the items of media content. The server may comprise a REST-based interface (API) for communication with the software application. SSL may be used for additional security. Further security measures to counter ‘click fraud’ may also be implemented, as discussed below.

The server could be provided centrally for all instances of software used by the system, or could be incorporated as an extension of existing architecture in the case where the provider of the software also provides a server for their specific software to be used by the system. This is particularly useful for the “smart warm calling” example implementation of the system, as will be described later on.

The server front-end is the part of the server-based system that the administrators see, from where the system is administered (adding apps and advertisements) and advertising metrics viewed. It may have one or more of the following features:

-   -   accessible through the web browser as HTML pages, which are         generated with PHP     -   provides a secure, password-protected area for administrators to         administrate the system     -   secured via HTTP basic authentication     -   allows app_ids to be generated (in more advanced         implementations, there is also provided means for revoking         app_ids/instance_ids)     -   allows advertisements to be created and for the corresponding         images to be uploaded in PNG image format and stored on the         server. In more advanced implementation, multiple images may be         supplied for different aspect ratios/pixel densities     -   allows a target URL to be specified for each advertisement     -   allows existing advertisements to be deleted from the server.     -   provides metrics on which advertisements have been clicked and         which host app(s) have been the source of the clicks         (potentially adapted to show impressions if the system tracks         impressions). For example:

Virgin Atlantic Coca Cola Nike T-Mobile Angry Goats 819 219 38 432 Pinstagram 1024 381 564 1003 Temple Dash 7 5 13 8 Cut the String 200 281 543 391

The server back-end of the server-side system typically comprises:

-   -   A series of PHP scripts which provide the REST-based API that         the client app uses to communicate with the server     -   A MySQL database which contains a listing of all the         advertisements in the system, as well as an audit trail of all         the click data

An example database schema is as follows:

Data hosts table App ID App name Developer name Developer email address Timestamp of creation instances table App ID Instance ID Timestamp of creation advertisements table Advert ID Client ID Advert target URL - where the advert takes the user when it's clicked Date uploaded reports table Report ID Instance ID Report start date Report end date clicks table Report ID Advert ID Clicks Impressions (if impressions are being tracked)

Media Content

The item of media content may comprise one or more of the following:

-   -   a video clip, animation, image, slideshow, text, hyperlink, web         page, URL, audio clip, ringtone, or any combination of the         above.     -   a combination of the above such as to produce a display         comprising text, at least one image and at least one hyperlink,         similar to a banner advertisement provided on internet websites.     -   an animated and hyperlinked image moving across the screen, such         as a hyperlinked image of an aeroplane say moving from right to         left, or a hyperlinked box of cereal pouring flakes into a bowl.     -   Speech, music or other audio may be a part of the media content         and may be played while the image or animation is displayed.

The item of media content may use .jpg, .gif, or any other suitable file formats, and may be written in html, php, javascript or any other suitable programming language.

The item of media content is stored (for example, in a database) on a remote server which provides the media content as required by the mobile device. Alternatively, the item (or items) of media content may be stored on multiple servers, locally or remotely, and periodically accessed by mobile devices.

In order to provide delivery of the media content from the server to the phone, each item of media content is encoded into a specific format to be transmitted and stored on the phone.

In the simplest implementation of a basic banner display format, each media content “payload” comprises an image, preferably provided in different sizes and at different DPI for different screen resolutions and aspect ratios (so that the server can select the most appropriate format of media content to send for a specific device to reduce cache/bandwidth wastage).

The media content item is “clickable” or otherwise is capable of triggering a further action (most commonly, opening a webpage).

Associated metadata is supplied in XML/JSON format which provides a URL that is launched if the media content is selected/clicked, along with some other data to by the app in order to select which item of media content to display.

In a more complex implementation, each “payload” includes multiple media types (e.g. image and audio file), or animation behaviour, along with more comprehensive metadata.

The more metadata is supplied with the media content, the more information is available to the server/app to select the most appropriate app to serve.

Generally, the media content is presented as an overlay with one or more of the following properties:

-   -   triggered when an incoming or outgoing phone call event is         triggered     -   is overlaid onto the incoming call screen     -   takes up the entire screen width and the height is set to a         fixed height in display pixels (determined during build)     -   displays a single PNG image advertisement (potentially selected         at random from the local advert cache), appropriately sized for         the overlay     -   records an impression for the advert (if impressions are being         tracked)     -   the image advertisement is clickable     -   is hidden once the call is accepted or rejected     -   is movable (this may not be possible in all versions of         operating systems and on all handsets) by pressing and dragging         it upwards/downwards, in order to support different types of         diallers on different handsets and operating systems/versions,         and so as not to obscure any caller ID information from the         native dialler     -   if the advertisement on the overlay is clicked, then after the         call has been accepted, rejected or completed the corresponding         website is launched in the default browser, and the click data         is recorded locally, ready to be sent to the server indicating         that the advert was clicked     -   in order to comply with guidelines or policies of the         network/operating system provider or app distributer, the         overlay contains information about the source of the advert and         any other details that may be required for compliance. This         information could be displayed in a pop-up dialog window where         necessary     -   has a button which can be selected in order to close it.     -   has buttons showing ticks and crosses, or other positive and         negative symbols, which can be selected in order to accept or         reject a presented offer.     -   has buttons (or other interaction means) through which the user         can indicate their preferences, where this preference may be         chosen out of an available options defined by the buttons.

Client Application

The call augmentation client application or app 100 is typically a stand-alone application which is pre-installed on the client device as part of the device configuration by a network provider. Alternatively, the app may be downloaded from an app distribution platform, library or store such as Apple iTunes or Google Play.

The app 100 registers itself to receive updates from the phone 10 operating system 72 any time when an incoming call event is triggered.

Alternatively, the call augmentation client application 100 may be embedded in or form part of a second software application which has a different primary function. The second application may be also be preinstalled on the client device or available to download and install subsequently.

In this case the call augmentation application 100 may be a compulsory or optional component of the second application, and if optional, may be provided as an opt-in or opt-out option during installation of the second application or at any time during use thereof.

Since users do not usually readily volunteer to accept advertising, an advantage of providing the application as part of a second application is that users will be persuaded to accept the advertisement application because of a desire for the features of the second application.

In some embodiments, the option is provided to have media content provided either via the call augmentation client application 100 or via regular in-app methods, with the further option provided to switch between the two. This may be an option which can be activated by the user and/or a configuration option which can be set in the app. Thus, a user may select whether media content, such as advertising, is displayed within a “free” app, or having media content, such as advertising, displayed on an incoming or outgoing call screen display. Alternatively, the user may choose to receive “smart warm calls” (as will be detailed later on) from the provider of the app or from third parties.

Background Service

The background service is initialised by the third-party app, and is configured to run automatically in the background continually, and to restart itself automatically if the device is restarted.

In order to ensure that the media content can be displayed on-screen immediately without delay, items of media content may be cached locally on the device.

There are a number of different ways to implement the caching system, preferably with a background service to maintain it so way that it does not grow uncontrollably, but at the same time ensuring that there is an appropriate amount of media content available locally on the device.

The device might not have 3G/Wi-Fi connectivity, or might not be able to use a data connection simultaneously to the incoming call, and either way mobile data connections are slow. Therefore, the background service periodically communicates with the server to download media content which is then stored locally on the device in a cache.

The cache is restricted to a particular maximum size and must be pruned periodically. In one example this is done is by checking to see if the cache reaches a particular size (e.g. 20 MB) and simply deleting older content to make way for the new (i.e. operating as FIFO queue).

A more complex version has the server flag each item of media content with an “expiry date” after which the item of media content will no longer be displayed and instead will be removed from the cache.

Algorithms

A set of algorithms are used to determine which items of media content are to be displayed on the phone for a particular call. In order to provide targeted media content the app selects a media content item based on a wide range of criteria, optionally including ones based on real-time information (e.g. current location, caller information, etc.)

In cases where the client app can only select media content from its local cache (not the server), which is a subset of the total media content library which sits on the server, a two-phase media content selection algorithm is used, part of which runs on the server and part on the client, which aims to fulfil the following two conflicting goals: —

-   -   1. Minimise cache usage and data transfer overheads.     -   2. Ensure that the best possible media content item is selected         on the device, without communicating with the server in         real-time.

In order for the media content to be displayed effectively, the server decides which media content items are sent to the handset in advance of the call to be cached (this could be several hours in advance, or even days). The server makes certain assumptions or predictions about which items of media content are best-suited to the user. This is based on information which is periodically sent from the app back to the server, or alternatively on static information. The server has a wide range of media content from which to choose, but makes a selection of which items to send to the client based on fairly limited information.

Alternatively, the subset of the media content library sent to the client app is selected randomly.

The client-side algorithm, on the other hand, has a much larger set of data upon which to make a decision of which item of media content to show as it has access to real-time data (e.g. caller info, date/time/location, etc.) but has a smaller subset of media content to choose from (i.e. it can only select an item of media content that already exists in the cache).

FIG. 10 shows an example of a media content item selection algorithm.

The two algorithms complement each other in order to achieve a balance between the two goals.

In the first phase, the server chooses which media content items (of those stored in server database 32) to send to the client. Then, in the second phase, the client selects the most appropriate media content item (from those stored in the cache 112) at the point of the incoming call.

Generally, the algorithms optimise the media item selection to maximise rates of user interactions or clicks. This may be based on prior market research or according to weightings determined from user interactions.

In some embodiments, up to four algorithms are used:

-   -   i) Server-side selection algorithm—Used to determine which         adverts should be sent from the server to the client's device to         be cached.     -   ii) Merge algorithm—Used to merge the new adverts received from         the server with the old adverts stored in the cache.     -   iii) Client-side selection algorithm—Used to determine which         advertisement should be selected from the cache and displayed on         the incoming call screen.     -   iv) Combination algorithm—Used by both the server-side and         client-side selection algorithms in order to combine multiple         sorted lists into a single list. This allows the adverts to be         effectively sorted by multiple factors.

FIG. 11 shows a further example of media content item selection algorithms.

Generally, both the client- and server-side selection algorithms apply a similar 3-step process whereby the adverts from the cache are sequentially filtered and/or sorted and then combined, so with the result that a series of adverts are selected (on the server) or a single advert is selected (on the client).

-   -   Filter—select those adverts from the cache matching certain         criteria.     -   Sort—sort them based on how closely they match the criteria.     -   Combine—once filters and sorts have been combined on the data in         a single operation, then a “combination” stage is needed to         combine all of the sorted data into a single list.     -   Select—select a single advert to display on the screen.

i) Server-Side Algorithm

The server uses an algorithm to determine which media content items to send to the client for local caching, based on factors such as:

-   -   Handset make/model and version of Android (operating system)     -   Previous items of media content shown     -   User preferences     -   Nature of the app providing the media content

In some embodiments, the media content item is selected at random.

Generally, the purpose of this algorithm is to choose those adverts from the extensive library of advertisements on the server that match the target device characteristics and factors, thus maximising the chances that the advertisements available on the device are relevant (and most likely to be clicked).

Inputs may include:

-   -   Factors received from the handset (and historic data from the         handset)     -   Adverts from the advertisers

Outputs may include a set of one or more advertisements, which are then transmitted to the client to be cached on the device.

The algorithm iterates through the advertisements on the server and builds a priority list of those that most closely match the data received from the handset. The top n advertisements (where n is the maximum cache size) are then collected and sent.

Filter & Sort

-   -   Filter by OS Version/Device Type     -   This filter, typically applied first, selects the most         appropriate advert for the device based on the version of OS         they are using and the device type, which consists of         information such as screen resolution, available screen space to         show an advert, screen aspect ratio, etc.     -   Filter by User Country     -   Using the IP address or historic GPS data collected from the         phone, it can be determined which country the user is in, and         the adverts can be filtered accordingly according to their         metadata.     -   Filter by User Location History     -   The server can use the device's location history in order to         extrapolate certain patterns (e.g. commuting patterns), which         can then be related back to advertising metadata.     -   Filter/Sort by User Advert History     -   The advert history consists of adverts that have been displayed         (and frequency) and those that have been clicked (and frequency)         for each user. Based on this information, adverts can associate         (or disassociate) themselves with one another.     -   In addition this presents the possibility that the server can         try different combinations of adverts if the current adverts         have not been so successful, or can continue to show the same         sort of adverts if they have been successful.

Selection

-   -   Top N Selection     -   The server-side sends the top N results after the sorts have         been applied, where n is a reasonable number of algorithms to be         transferred over the Internet. N could also relate to the         frequency of updates (i.e. the more recent the last transfer,         the lower the N value).     -   In some embodiments the client itself defines N based on its own         calculations of how many “fresh” adverts are needed, based on         the expiry of algorithms or whether they have already been         selected/displayed, etc. (a side effect of this being that the         merge step can be omitted).

ii) Merge Algorithm

The purpose of this algorithm is to merge the new adverts received from the server with the old adverts already stored in the cache. This algorithm is run every time the client receives an update from the server.

Inputs may include:

-   -   New adverts received from the server     -   Old adverts retrieved from the cache     -   Local device factors (possibly—although the server should         already be aware of most of these and would have factored them         into the update).

Outputs may include a new set of adverts (old and/or new) which are then stored in the cache.

The algorithm iterates through each of the new advertisements received from the server and each of the old advertisements retrieved from the cache, filters them and sorts them into a list. Depending on the available cache size, the top n are selected.

In an alternative implementation of the system where the client is able to delete its own adverts when they are deemed to be no longer relevant, and is able to specifically request a number of new adverts from the server, the merge algorithm is not actually required: The client can simply delete N adverts from local storage, and request a new set of N adverts to replace them, without needing to merge. This also saves on bandwidth, as only the required number of adverts actually needs to be transmitted. The downside of this approach is that the client must perform more processing initially in order to determine which adverts to delete and how many slots are open.

iii) Client-Side (Selection) Algorithm

The client-side algorithm, meanwhile, decides which item of media content to select from the device local cache. It is able to do this based on real-time information such as: —

-   -   Location of the callee (via GPS)     -   Location (region) of the caller (via phone number)     -   Current date and/or time     -   Specific incoming and/or outgoing call events

For example, the app could use caller-based methods to display location- or situation-based information or to implement “adversarial” marketing based on sponsorship of particular factors.

In some embodiments, the media content item is selected at random.

Generally, the purpose of this algorithm is to select a single advertisement to display on the incoming call screen from the cache, based on the best available information on the device, which may include real-time information such as GPS location and factors to do with the incoming call.

Filter & Sort

-   -   Filter/Sort by Caller Phone Number     -   The advert metadata specifies a list of phone numbers (or phone         number regular expressions—up to some level of detail) that it         should be triggered for. When the call comes in, a check is done         to see which adverts should be triggered for this specific         number.     -   The more specific the list of phone numbers (or the more         concrete the regular expression) the higher position it is given         in the sort.     -   Filter/Sort by Caller Location     -   The caller location can be approximated by examining the         caller's area code (or international country code) and this data         can then be matched with advertising metadata to determine which         advert should be shown. Some adverts may only be relevant to         specific countries or regions. The adverts can be sorted based         on the physical proximity of the advertised content or service         to the location of the caller, and then by how specific they are         to a particular region.     -   Filter/Sort by User Location     -   The advert metadata provides a point and catchment radius in         metres, or a 2-dimensional bounding box specified in latitude &         longitude. The current GPS location data is retrieved and a         check is done to see which adverts cover the current location.     -   The location data can either be coarse (i.e. fairly inaccurate         using cell triangulation, but faster to retrieve) or fine (i.e.         more accurate via GPS, but slower to determine). The adverts can         be sorted by how far they are from the current location—or if         their location is specified by a bounding box, then how small         the bounding box is.     -   Sort/Filter by Date & Time     -   Certain adverts might be only suitable for display during         specific times or dates, based on the metadata. (For example,         promotions that run for a fixed time, or stores that are open at         specific hours). The date and time in the advert metadata can be         specified as a specific time, or a range.     -   Sorting is a combination of (a) the size of the date/time window         (the smaller the date/time window, the higher the sorting         priority) and (b) how close to the target date/time (if there is         one) the user is at that moment (this can also be specified in a         forward-looking only mode).     -   Sort/Filter by Server Factors

The client can also optionally apply many of the same filters that run on the server, such as personal browsing/call history, etc.

Selection

-   -   Sequential Selection     -   An ordering is maintained for each advert, and the adverts are         iterated over sequentially, which prevents the same adverts from         being shown repeatedly (which can happen with Weighted Selection         and Top Selection).     -   Random Selection     -   An advert is selected at random. This usually requires very         robust filters to be in place, because the sorting order is         ignored leaving just the filters.     -   Top Selection     -   The top-ranking advertisement is selected. This is not a good         idea unless there are a large number of adverts available to         choose from with a wide variety of factors.     -   Weighted Selection     -   In this algorithm, the advertisements higher on the sorted list         are weighted the most, with subsequent positions on the sorted         list having a probability of selection that decays         exponentially.     -   The following is an example of the weighting and subsequent         probability of selection for a list of five adverts:

Position on List Weighting Probability of Selection 1 100 0.52 2 50 0.23 3 25 0.13 4 12.5 0.0625 5 6.25 0.032

iv) Combination Algorithm

The purpose of this algorithm is to combine multiple filtered/sorted lists into a single filtered & sorted list from which a selection can be made.

Inputs may include:

-   -   Filtered/sorted list from each factor in the algorithm     -   Weights for each factor (if applicable)     -   Hard-coded directives, such as the position-weight decay         function

Outputs may include a single sorted & filtered list of adverts from which a selection can be made.

The filtering, sorting and selection algorithmic components are specific to each algorithm (and interchangeable), but the combination algorithm is common both the client-side and server-side algorithm and consists of combining multiple sorted lists of adverts into a single sorted list, so that a selection can be made.

For example, supposing we have two factors X and Y by which we want to sort advertisements. X could be, for example, “adverts sorted by distance from the current user”—the higher on the list the advert is, the closer it is to the user geographically. Y, on the other hand, could be “adverts sorted by past history” where the higher on the list the advert is, the more suitable it is based on the user's advert history.

First of all, we can sort them by X:

  Sorted by X Advert 2 Advert 3 Advert 1 Advert 5 Advert 4

Then, we can independently sort them by Y as well:

  Sorted by Y Advert 4 Advert 1 Advert 2 Advert 3 Advert 5

The result will be two, completely separate lists, which makes it difficult to select which advert would be the best one to show to the user. Even if it were desired simply to select the “top” advert, the two sorted lists will not agree on which is the “top” one.

Therefore, these two lists are combined. A combination algorithm which shows how this can be achieved is now described.

In the above examples, each advert is given a position-weight where 5 is the top of the list and 1 is the bottom. The position-weights for X and Y are then added to produce an overall weight, which then produces a new sorted list as a combination of the original lists.

(Weight for X) + Sorted by Y Weight for X Weight for Y (Weight for Y) Advert 1 3 4 7 Advert 2 5 3 8 Advert 3 4 2 6 Advert 4 1 5 6 Advert 5 2 1 3

By taking the combined (added) weights, the following combined list is created, from which a selection can be made according to the selection algorithms described previously:

  Sorted by X + Y Advert 2 Advert 1 Advert 3 Advert 4 Advert 5

However, this particular algorithm is heavily simplified and may not be suitable for real-world implementation. In particular:

-   -   Both X and Y were treated completely equally. In the real world,         one would probably want to weight one factor more than another.     -   This algorithm only handled two factors, but it may be desirable         to handle more.     -   The position-weight of each advert was calculated by simple         linear decay, but this could be modelled as exponential, etc. to         give more weight to higher results.     -   There may need to be a “tiebreaker” for handling cases where         after combination, two adverts have the same weight (in this         case, we simply inserted them randomly).     -   This algorithm only handles cases of sorting, not filtering         (although it can be assumed that filtering is simply the process         of applying an unsuitable advert with a zero weight).

According to a further example, a combination algorithm is also provided, where for an advert a with 3 factors {x, y, z}:

w _(a) =w _(x) w _(a) _(x) +w _(y) w _(a) _(y) +w _(z) w _(a) _(z)

where:

-   -   w_(a) is the final position-weight of advert a.     -   w_(x) is the pre-defined relative weight of factor x.     -   w_(ax) is the position-weight of advert a on the sorted list for         factor x.

An example flow of how the advertising selection system works end-to-end is as follows:

-   -   1. Assuming the client app has 50 adverts stored locally in the         cache, and for simplicity we assume that all adverts are the         same size and that the client capacity is for 50 adverts.     -   2. The client is informed that it is time for the periodic         update with the server, so it requests an update from the         server.     -   3. In addition to the request, the client also sends to the         server information about which adverts have been shown, and         which have been clicked since the last update. It also sends         information about their version of Android and handset type and         approximate geographical location over the last 30 days.     -   4. The server's advert library is then sorted and filtered by         these factors and then combined into a single list on which the         Top N selection algorithm is used to select the top 50 adverts.     -   5. The client receives the 50 new adverts, and uses the merge         algorithm in order to determine which adverts to delete from the         cache, and which to save—and equally which adverts to “merge in”         to the cache from the server update, and which to ignore.     -   6. The merge algorithm completes and the client now has a set of         50 up-to-date adverts in its cache.     -   7. A call comes in, the client now sorts and filters the adverts         from its cache both by the current user location as well as the         date/time and then applies the combination algorithm to produce         a single sorted list on which a weighted selection is done in         order to select a single advert from the cache to present to the         user.

The above is only one possible example implementation of the system.

Software Development Kit

In some embodiments, a SDK is made available online, which developers can download to bundle this technology with their own app. The SDK bundles the client-side components, comprising the background service and app.

These components can either be bundled directly inside the third-party app package, or can be included as a separate package which is installed by the third-party app (in particular, the latter approach simplifies dealing with multiple apps on the same device using the SDK).

In the case where the software application is provided as part of a second software application, the software application may be provided as a software development kit (SDK) made available to software developers online or elsewhere. The developers of the second software application would therefore install the software application as part of their second software application using the SDK. For example, developers of a game app may use the SDK to install the software application of the present invention as part of their game app. An advantage of this arrangement to the developers is that they gain revenue by enabling advertisements of a third party to be displayed on the incoming call screens of users of the game app. An advantage to the third party (the providers of the advertisement) is that their advertisement is displayed on the incoming call screens of users who download the game app, and they may pay for this advantage according to the number of impressions of their advertisement shown (CPM), or the number of times a user selects their hyperlink (CPC), or any other means.

Generally, the SDK may offer one or more of the following features:

-   -   distributed as a downloadable package that can be incorporated         into a third-party app, referred to as the host app     -   initialised using a simple API which uses an app_id to         initialise the app with a unique identifier for the host app     -   Upon initialisation, the SDK verifies the app_id and requests an         instance_id for this specific installation of the app from the         server which is then stored on the device     -   Once the SDK has verified the app_id and received the         instance_id, the software application (Incall) is activated on         the app     -   If the app cannot validate the app_id because it is rejected as         invalid, then an error message is displayed and Incall is not         activated     -   If the app cannot validate the app_id because there is no         internet connection available, then no error message is         displayed, Incall is not activated, and Incall will attempt to         validate the app_id next time the initialisation routine is         called     -   If the app cannot request an instance_id because there is no         internet connection available, then no error message is         displayed, Incall is not activated, and Incall will attempt to         request an instance_id next time the initialisation routine is         called.

Typically, the SDK is bundled with the host app; as such it is automatically uninstalled with the host app.

In some configurations (particularity where “smart warm calling” is used, as will be described later) the SDK may be integrated into an already installed app via a software update. This SDK may, optionally, be used by third parties in addition to the party providing the app, subject to the end user signing a license agreement. A number of items of media content may be provided as part of the software update so that the system can work immediately following the update.

Security

Click fraud is a problem encountered by all advertising networks, that is, how to establish that the “clicks” being reported to your server are actually genuine clicks, and not malicious users who have figured out how to game your system in order to report thousands of fake clicks?

There are two main ways of gaming the system:

1. developers manually clicking their own ads in order to record clicks. 2. developers determining the server's API in order to submit fake click reports.

There are ways to mitigate click fraud, however as with any network there is no 100% secure method of ensuring that clicks are genuine.

For the present system, the challenge of preventing click fraud is even greater, as the application code is downloaded and run locally on the user device (which they can exploit far more easily) and in a delayed reporting system, this is ideally done in an offline environment, periodically syncing with the server.

One way to address this is by establishing a sufficiently detailed audit trail as so to make any click fraud fairly easily recognisable.

Firstly, each click report contains the app_id. This is generated by the server and is hard-coded into the host app.

Each click event must contain an app_id which relates to the host app on the device.

Therefore, the app_id can be used to establish an audit trail, to analyse click behaviours coming from a specific app.

However, the app_id is potentially a weak measure because it can easily be extracted by specialised tools to extract data (in particular, strings) from the app binary. A malicious developer could use the app_id to thousands of fraudulent clicks. Without further analysis, it may be impossible to determine whether this is one user sending illegitimately submitting thousands of clicks, or a thousand users legitimately clicking one advert each.

To mitigate the shortcomings of using the app_id alone, the instance_id is introduced as an additional measure in order to uniquely identify each instance of the app.

Upon initialisation, the SDK requests a unique instance_id from the server, and this is stored on the device for the lifetime of the app. In the event the app is uninstalled and re-installed, a new instance_id is generated, however the instance_id persists during an upgrade.

By using the instance_id, we can now determine whether the thousand clicks (from the previous example) come from one user (i.e. one instance) clicking a thousand adverts, or one thousand users (i.e. one thousand instances) clicking one advert.

However, there is nothing to stop a malicious user from generating a single app_id, 1,000 instance_ids and then submitting click reports of 1 click each. This can be mitigated by:

-   -   1. Checking the number of clicks per instance_id. If a single         instance_id is generating an abnormally high number of clicks,         this could be indicative of click fraud.     -   2. Checking the timestamps of the instance_id generations. If         they were all generated in a single short burst over a very         short timespan (i.e. matter of minutes), then it is likely that         the instance_ids were generated fraudulently via a script.     -   3. Checking the IP addresses of the instance_id generations. If         they were all generated from the same IP address, then it is         extremely likely that the instance_ids were generated         fraudulently by the same user.     -   4. Checking the Android app download figures directly with         Google. In the event of a click fraud investigation, a developer         could be asked to prove their installation figures from their         Google Developer Console. If the number of instance_ids vastly         exceeds the number of downloads & installations, then it is         extremely likely that the instance_ids have been fraudulently         generated.

Therefore, by combining the app_id with the instance_id, and also looking at the IP address of the click report (which cannot be spoofed), there is enough data to mitigate the risks associated with most common forms of click fraud.

A further example incorporates the following features:

-   -   Using the device's IMEI number to further validate click         information.     -   Using triggers on the advertiser's website to validate         click-throughs as being genuine.     -   Using a one-time code based on the instance_id (or a         server-based nonce).

Therefore, the SDK simply reports the app_id and instance_id for each click/impression, and the server stores an audit trail of app_ids, instance_ids, timestamps and IP addresses in its database in order to facilitate manual investigations and to support a possible future implementation of an automated detection algorithm.

In addition, all communication between the app and the server is secured via SSL to prevent eavesdropping and man-in-the-middle attacks.

In some embodiments, clicks are accompanied by the IP address of the source of the click, in order to make it easier to monitor for click fraud.

Privacy

It is important that the various approaches discussed for collecting and uploading potentially sensitive user data to the server, which may include personal information, are legal and in-line with appropriate guidelines, and also that such information is properly communicated to the end-users to allow them to make an informed decision as to whether or not they wish to share their personal information.

Operation

FIG. 5 shows an example implementation in flowchart form of the client application.

-   -   S1. When a call occurs from a second party to the user of the         mobile device, an incoming call event is triggered by the         operating system and the dialler sends notification 110 of the         incoming call event to launch the application 100.     -   S2. The augmentation application 100 is launched.     -   S3. Algorithm determines which media content item to display         -   This may involve the application sending a media content             request 102 to a cache 112. The cache 112 is a local store             of media content on the mobile device. Upon receipt of the             media content request the cache sends the media content item             108 to the application 100.         -   As described above, in some embodiments, the mobile device             periodically accesses the remote server and downloads             updated media content for downloading updatable information.     -   S4. Media item overlay is displayed, i.e. a view is attached to         the phone's window manager and is overlaid onto the incoming         call screen.         -   Since a call is occurring, the screen will usually be             displaying an incoming call screen image or callerID 104.             The application interacts with the windows manager (or other             appropriate component of the operating system) of the mobile             device to enable the media content to be prioritized over             the incoming call screen and therefore the media content             image 101 to be overlaid on the incoming call screen image             104 such that the screen 106 displays the media content             image. This change in priority may be conducted by changing             the respective display z-orders of the item of media content             image 101 with respect to that of the incoming call screen             image 104.     -   S5. Is the call accepted/rejected/timed out? i.e. the app waits         until the call is answered or rejected, at which point . . .     -   S6. The view is removed from the phone's window manager.     -   S7. The app remains in the background for the duration of the         call.     -   S8. Was the media content item clicked?     -   S9. If yes, the user clicked on the media content item prior to         accepting the call, then a browser window is opened after the         call which takes the user onto a specific website.         (Alternatively, this could be a different action other than         opening the browser, such as dialling a number, etc.)     -   S10. Otherwise, the app terminates itself (and optionally         reactivates itself after the call).

FIGS. 6, 7, 8 and 9 show examples of telephone call augmentation.

FIG. 6 shows an Overlay Example 1: Movable banner. In this example, the media content item is shown as a traditional banner ad which can be moved upwards and downwards by the user (or set programmatically) so that it does not occlude the caller information and call accept/reject buttons. It could also be horizontally/vertically resizeable.

FIG. 7 shows an Overlay Example 2: Custom animation. In this example, the overlay does not necessarily need to be a rectangular shape, and indeed in many cases it would be more desirable to have the objects more fluid in order not to obscure the call screen. In this example, the media content item is shown as an aircraft which zooms across the screen right-to-left upon the incoming call.

Many different shapes or types of media (image/video/3D animation, etc.) that can be displayed on the screen, e.g. a cereal box which appears from the bottom of the screen, propelling cornflakes all over the screen.

FIG. 8 shows a further example, showing the overlay/media content item with “host” app origin, further information and ‘close’ buttons. User clicks on the media item in the immediate vicinity of the close button may in some embodiments be interpreted as ‘near-miss’ attempts to close the overlay.

FIG. 9 shows an overlay example for a limited offer, showing the overlay/media content item with tick and cross buttons 201, 202, an indication of location 203 and “Stop Ads?”/‘close’ button 204. This example is particularly useful for offers which are specific to a particular location or time. The user may take up the offer by pressing the tick button 201, or reject it by pressing the cross button 202. Pressing the “Stop Ads?” button 204 may redirect the user to a page where they can purchase a premium version of the developers' application which does not include the bundled SDK.

Delay Feature

In a preferred embodiment, the media content item comprises at least one hyperlink with a delay feature, such that when a user selects (or “clicks”) the hyperlink before answering a call, or during a call, the call is not interrupted and the user's viewing of the destination website, webpage or URL defined by the hyperlink is delayed until the end of the call. Upon ending the call, the mobile device screen displays the website at the destination specified by the hyperlink.

In some embodiments, the destination page may be “pre-loaded” by being navigated to in the background during the call by the browser of the mobile device.

Alternative implementations of the delay feature include:

-   -   immediate navigation to and display of the destination, but the         incoming call screen, or the displayed part of the incoming call         screen, may still be accessible and usable     -   only the portion of the screen displaying the media content item         immediately displays the destination website; the rest of the         screen may display the destination website only at the end of         the call     -   selecting or clicking the hyperlink may both cause the browser         to navigate to and display the destination website, and answer         the call. In this case, navigation to and/or display of the         destination website may be immediate or delayed until after the         call. An advantage of this is that the user can, with one         selection, answer the call, and navigate to the desired         destination website. The destination website will either stay on         the screen until the end of the call or be displayed at the end         of the call, at which time the user can view it.

Android Implementation

Depending on the specific operating system in question, the components, implementation and terminology may differ slightly from platform to platform. The description used in this document is based loosely on the Android paradigm. A basic prototype which provides an incoming call screen overlay on the Android platform will now be described.

-   -   1. The app registers a BroadcastReceiver to receive the         android.intent.action.PHONE_STATE intent with maximum priority.     -   2. When the intent is received by the BroadcastReceiver, the         TelephonyManager.EXTRA_STATE information is retrieved from the         intent's extras.     -   3. If the state is equal to         TelephonyManager.EXTRA_STATE_RINGING, the app starts a new         Service.     -   4. Upon starting, the Service gets the WINDOW_SERVICE system         service and adds a new View with the relevant content. It also         registers itself as with a new IntentFilter to receive a custom         IDLE_STATE action.     -   5. The Service also handles updating the view with the relevant         media content, along with any user interaction (e.g. clicking).     -   6. When the BroadcastReceiver receives a further intent with the         TelephonyManager.EXTRA_STATE intent equal to         TelephonyManager.EXTRA_STATE_IDLE (i.e. the call has been         accepted or rejected) then a new intent is sent with the         IDLE_STATE action.     -   7. The Service receives the IDLE_STATE action and terminates         itself.

In order to capture the post-call event (in order to display the media content, if it was clicked), the prototype can be extended to maintaining a boolean on the Service of whether the media content item was activated or ‘clicked’.

It is also possible to retrieve not just the current state from the intent on the BroadcastReceiver, but also to compare it to the previous state (which was earlier stored, as the BroadcastReceiver is triggered independently each time the android.intent.action.PHONE_STATE intent is received) in order to determine when the call has ended.

A more complete implementation uses a background service and caching system for the media content, along with the relevant algorithm to select the most appropriate item of media content.

Different versions of Android place the call accept/reject buttons differently, and OEMs have the ability to replace the incoming call screen with their own alternatives (e.g. HTC's Sense & Samsung's TouchWiz). Therefore, the media content item screen overlay is placed and sized differently according to each handset and version of Android in order to ensure that the caller ID and accept/reject buttons are accessible. The app is therefore customised for compatibility with each version of Android and each handset.

Support for Multiple Parties

The SDK may also facilitate deployment from multiple third-party apps.

The challenges this poses are as follows: —

-   -   1. The call screen is generally only capable of displaying one         item of media content per call, therefore the deploying apps         must cooperate (or indeed compete) to ensure that only one item         of media content is shown at a time.     -   2. There needs to be a fair way of distributing the revenue         between the multiple third-parties.

In other words, each time a call comes in, there is one media display slot on offer, and therefore the client-side app must introduce an additional selection stage in order to decide which media content item is selected for display.

A number of example approaches that are used to handle multiple apps deploying the call-handling facility on the same device are described below (those models which only work in a CPM scenario are labelled accordingly):

(As previously, CPM or cost-per-mille refers to the number of times the media item is shown; CPC or cost-per-click refers to or the number of times a user selects the associated hyperlink).

Monopoly Model (CPC/CPM)

The monopoly model is both the simplest and least fair: the first app which uses the SDK is granted all media display slots on the device, to the exclusion of any other apps that may be installed at a later date.

If an app tries to activate the media content display and another app using the SDK is already installed, the app will be informed that the activation failed, and instead would be forced to provide some other means of media display (or forgo media display entirely).

Sequential Model (CPM)

In the sequential model, the SDK maintains a list of all third-party apps which use the SDK. When a call comes in, the SDK cycles through each app displaying an item of media content pertaining to a specific app, one per call giving each app one slot in turn.

Probabilistic Model (CPM)

In the probabilistic model, the SDK maintains a list of all third-party apps which use the SDK. When a call comes in, the SDK selects one at random from the list and displays it.

Financial Distribution Model (CPC/CPM)

In the financial distribution model, all of the CPC/CPM proceeds are put into a central pot which is then divided between the apps installed.

Bid Model (CPC/CPM)

In the bid model, each media content provider (or app developer) “bids” for the media display slot through an automated auction system.

Generally, Incall is provided as a SDK (Software Development Kit) in the form of a source code component that is bundled with third party apps in order to provide pre- and post-call advertising.

Each Incall-enabled app is packaged with the SDK before distribution within, in the example of an Android OS, an APK (Android Package) file, therefore each enabled app has its own separate copy of the SDK (which is referred to as a separate “instance” of Incall).

The SDK has three key functions:

-   -   1. To intercept the incoming call screen to add advertising and         to detect when the call has been ended to display the post-call         advertisement.     -   2. To periodically sync with a central server to retrieve a         fresh set of advertisements to display to the user.     -   3. To report back to the server the number of clicks and         impressions for each advert.

The syncing function of the SDK may allow a media content provider to bid for media display slots and quickly supply their media content to users.

Although there may be multiple instances of Incall on a single (Android) device (due to the presence of multiple enabled apps), only one instance of Incall should be responsible for the above three functions. If each instance were to act independently with no co-ordination between them, then the result would be:

-   -   1. Multiple instances would conflict with each other when trying         to add adverts to the call screen. The likely outcome would be         that multiple adverts would be shown on top of one another.     -   2. Multiple sync events would take place, which would consume         data allowance and battery.     -   3. Clicks and impressions would be reported inaccurately: due to         conflicting instances of the SDK, they might be recorded         multiple times, or not at all.

An algorithm is accordingly provided to allow multiple instances of Incall to coordinate with one another so that a single (“master”) instance of Incall is responsible for displaying the adverts, syncing with the server and reporting the clicks and impressions.

The algorithm incorporates also the following features:

-   -   Allow inter-instance communication so that the other (“slave”)         instances are able to contribute app metrics to the master         instance for transmission to the server     -   Be decentralised so that there is no reliance on any third-party         components (which could be uninstalled) or shared log files         (which could be removed or tampered with)     -   Give precedence to instances of Incall that are a more recent         version.     -   Switch instantaneously (or at least minimise any delay) in         switching between instances so that Incall is continuously         active on the device.     -   Be invulnerable to outside apps interfering with the         master/slave coordination process.

The following three different example algorithms for master/slave coordination are described below (in overview and using pseudo-code):

-   -   i) intent-driven algorithm     -   ii) log-driven algorithm     -   iii) server-driven algorithm

A further option iv) is also described.

Once multiple instances are able to coexist, coordinate and cooperate on a single device, business logic is used to divide the revenue from clicks and impressions between the multiple instances.

i) Intent-Driven Algorithm

The intent-driven algorithm uses Android intents to provide a decentralised method of coordinating between multiple Incall instances.

The Android documentation describes an Intent as “an abstract description of an operation to be performed.” Intents are commonly used either locally to trigger events between different components of an app, or system-wide to communicate between multiple apps. Put simply, an intent can be thought of as a sort of message which can be sent from an app to all other apps on the device. For example, the intent

-   -   android.intent.action.VOICE_COMMAND         is sent when an app wants to start accepting voice commands.         Android has built-in support for voice commands, but by         registering and responding to this intent, other third-party         apps can receive them too and offer to provide voice command         services.

In the intent-driven algorithm, system-wide broadcasted intents are used in order to facilitate communication between slave instances and their master. An intent is in effect an “event broadcast”. One app (strictly speaking, a component of an app), sends out the intent, and any other apps (strictly speaking, components of those apps) which are registered to receive that intent will pick it up and can take action accordingly.

Advantages:

-   -   Technologically elegant.     -   Decentralised.     -   Using intent “extras” it's possible to attach an additional         payload to the intent which makes it easy to collect metrics         from other Incall-enabled apps by passing the metrics as intent         extras.     -   Intents are event-driven, so no need for polling.

Disadvantages:

-   -   Using system-wide intents, there is no way to prevent a         malicious third-party developer from triggering their own         intents and disrupting the natural application flow.     -   Void period when transitioning instances caused by waiting for         intent interval.

In terms of implementation, upon installation, each instance of Incall by default starts in slave mode (unless it has previously recorded itself as being a master instance in preferences), and registers a BroadcastReceiver to receive a com.getincall.HEARTBEAT intent, sent by a master instance to inform the slave instances that it is active.

It then also defines a variable sleepTime which is a random number in the range heartbeatInterval+1 to maxSleepTime.

heartbeatInterval and maxSleepTime are constants defined as follows:

-   -   heartInterval is the constant, pre-defined time between         “heartbeats”. The com.getincall.HEARTBEAT intent must be         activated once every heartbeatInterval by the master Incall         instance to tell the slaves that it is still active on the         device.     -   maxSleepTime is the constant, pre-defined maximum time that         should be allowed to elapse without any master Incall instance         asserting itself.

It is desirable that maxSleepTime−heartbeatInterval>10000 to ensure a sufficient number of random variations for the sleep timer, thus staggering when each instance wakes up to ensure that two instances don't wake up at the same time and both try to become masters simultaneously.

If (and each time) the com.getincall.HEARTBEAT intent is received, sleepTime is reinitialised to a random number in the range heartbeatInterval+1 to maxSleepTime and the instance stays in slave mode. This is because if a heartbeat is detected, then there must still be an active master instance on the device.

If the heartbeat is not received, or if the app starts and reads from preferences that it is the master, then it takes over all the Incall responsibilities on the devices, such as displaying ads, syncing and reporting. It also registers a BroadcastReceiver to receive the com.getincall.RESIGN_MASTER intent, which can be broadcast by any slave instance in order to force the resignation of the master instance (for example, to enforce version precedence) at which point it returns to a slaved state.

An example implementation is as follows:

-   -   1. An Incall instance is installed on the device. It begins in         slave mode, listening for a heatbeat over a random interval.     -   2. No heartbeat is received in that interval, so it now becomes         the host and starts broadcasting a heartbeat every         heartbeatInterval.     -   3. Incall instance B is now downloaded and installed on the         device, and it too begins in slave mode.     -   4. Because B keeps receiving the heartbeat from A within its         sleepTime interval, it stays in slave mode.     -   5. Incall instance C is now also downloaded and installed on the         device, also beginning in slave mode.     -   6. Because C also receives A's heartbeat within its (random)         sleepTime interval, it too will stay in slave mode.     -   7. At some point, A is now uninstalled from the device, causing         its heartbeat to stop.     -   8. Because sleepTime_(B)≠sleepTime_(C) (since they were both         chosen randomly), either B or C will “time-out” before the         other.     -   9. In this example since sleepTime_(B)<sleepTime_(C), B's timer         ends first, so it now becomes the master and broadcasts the         heartbeat, which is received by C which then continues to run in         slave mode.

As pseudo-code:

const HEARTBEAT_INTERVAL = 1800000 // 30 minutes const MAX_SLEEP_TIME = 2400000 // 40 minutes heartbeatReceived = false isMaster = false function onFirstRun( ) {    on Boot( ) } function onBoot( ) {    isMaster = preferences.read(“isMaster”)    if (!isMaster) {       becomeSlave( )    } else {       becomeMaster( )    } } function onIntentReceived(intent) {    if (intent = = “com.incall.HEARTBEAT”) {       heartbeatReceived = true    } else if (intent = = “com.incall.RESIGN_MASTER”) {       becomeSlave( )    } } function becomeSlave( ) {    isMaster = false    preferences.write(“isMaster”, false)    register_to_receive(“com.incall.HEARTBEAT”)    do {       heartbeatReceived = false       var sleepTime = rand(HEARTBEAT_INTERVAL+1,    MAX_SLEEP_TIME)       sleep(sleepTime)    } while (!heartbeatReceived)    becomeMaster( ) } function becomeMaster( ) {    is Master = true    preferences.write(“isMaster”, true)    register_to_receive(“com.incall.RESIGN_MASTER”)    do {       sleep(HEARTBEAT_INTERVAL)       broadcast_intent(“com.incall.HEARTBEAT”)    } while (isMaster) }

ii) Log-Driven Algorithm

The log-driven algorithm is similar to the intent-driven algorithm, but instead of using a decentralised algorithm and waiting for real-time intents, it instead polls shared log file to coordinate between the multiple Incall instances.

Advantages:

-   -   Simple—just a single shared file text file needed.     -   Traceable—can be used to store a record of         installations/uninstallations.

Disadvantages:

-   -   Log files must be stored outside of the app directly (i.e. not         in Internal Storage), leaving them open to user/other app         tampering or deletion.     -   If log file is stored on SD card and the card is ejected, the         log is lost.     -   Must poll log file on disk which is inefficient (wastes CPU and         battery).     -   Void period when transitioning between master instances caused         by polling interval.

Regarding implementation, upon installation, the Incall instance checks for the presence of the log file and begins reading it from top to bottom. If there is no log file, one is created and the current instance records itself as the master and writes to the log.

Each instance still uses a randomised sleepTime variable like in the intent-driven algorithm, but the range is from minPollingInterval+1 to maxPollingInterval where maxPollingInterval−minPollingInterval>10000 to ensure a wide number of values to ensure staggered polling between each instance.

The master app is responsible for writing an entry into the log file every minPollingInterval. Therefore, if after minPollingInterval+1, no update has been made to the log file, then similar to the heartbeat in the intent-driven algorithm, this would be evidence that the master instance is no longer running on the device, and clears the current instance to upgrade itself to master status.

An example implementation is as follows:

-   -   1. At time 18877180, Incall-enabled app A (package name         com.alpha.A) is installed on the device and writes to the log         file every minPollingInterval=100000.     -   2. Another Incall-enabled app B (com.alpha.B) is installed on         the device and starts polling the log file at randomised         intervals within the above specified range.     -   3. At time 19189243, A is uninstalled from the device, which         means that its last log entry is at 19177180. The log file looks         like this:

Time Master instance package name 18877180 com.alpha.A 18977180 com.alpha.A 19077180 com.alpha.A 19177180 com.alpha.A

-   -   4. When B finishes sleeping and next polls the log file (which         happens to be at time 19178465), there has been no update from         A, and so B is able to upgrade itself to master mode.     -   5. B then updates the log file every minPollingInterval=100000,         which means that continuing directly from above, the next         entries in the log file appear as follows:

19178465 com.beta.B 19278465 com.beta.B 19378465 com.beta.B

At some point it is necessary to prune the log to avoid it becoming excessively long (this can be done after just a single entry, as it is not necessarily required to maintain a long and detailed history).

The above does not take into consideration: (a) contribution of any metrics or extra information from the slaves to master instance, and (b) decisions based on version numbers, etc. For this reason, the intent-driven algorithm may be a more flexible and decentralised alternative to the log files algorithm.

The pseudo-code is similar to that for the intent-driven algorithm, only writing to the log file instead of a heartbeat, and polling at random intervals instead of waiting random intervals for intent broadcasts.

iii) Server-Driven Algorithm

The Server-Driven Algorithm involves each instance interrogating the Android OS for the installed apps and monitors for installations, uninstallations and upgrades and then communicates that information to a server (via an API) and the server then informs each instance whether it should be a master or slave.

Unfortunately, Android does not allow an app to detect when it is about to be uninstalled by the user, or take any actions when the uninstall itself takes place. However, all apps can retrieve a list of the package names of currently installed on the device, and all apps other than the one being installed/uninstalled/upgraded can listen for the following intents:

-   -   android.intent.action.PACKAGE_ADDED     -   android.intent.action.PACKAGE_REPLACED     -   android.intent.action.PACKAGE_REMOVED

Each Incall instance sends these package names to the server (which maintains a list of package names which are enabled, ordered by precedence) and the server then responds to each instance whether it should be a master or slave.

Advantages:

-   -   Instant switching between instances, because this approach is         event-driven by monitoring for the actual package         install/upgrade/remove operations (and therefore more         efficient), there is no need for polling.     -   Because decisions are made by the server rather than on the         device itself, it would be very difficult for a malicious         third-party app to interfere with this process.

Disadvantages:

-   -   Entire app package list must be sent to the server, which could         be a privacy concern (could send package hashes instead, but         this would still be a privacy issue).     -   Server must maintain list of package names, versions,         precedence, etc. which requires extra server-side logic.     -   Internet connection is required to determine mode each time a         package operation takes place.

In terms of implementation, the app registers to receive the intents

-   -   android.intent.action.PACKAGE_ADDED     -   android.intent.action.PACKAGE_REPLACED     -   android.intent.action.PACKAGE_REMOVED         in order to check when the package list changes, and also         immediately sends the package list to the server along with the         name of the current instance's package name.

The server then cross-references this information against its stored package list, ignores any packages which are not Incall-enabled and uses a priority list to report back to each instance whether they should be the host or not.

Since each Incall instance on the device carries out these identical steps, it is not necessary for the server to actually maintain any state for each Incall instance, only to maintain an ordered package list of all Incall-enabled apps.

An example implementation is as follows:

-   -   1. A (com.alpha.A) is installed on the device (which is an         Incall-enabled app). It registers to receive the package         add/replace/remove intents, and then sends its package list to         the server, which consists of [com.magnum.Fighter,         com.facebook.Facebook, com.alpha.A] along with its own package         name (com.alpha.A).     -   2. The server receives the instance package name and full         package list and cross-references it against its own package         list.     -   3. In this case, com.alpha.A is the only installed app which is         an Incall instance, so the server API responds telling the app         to become the master.     -   4. At some point in the future, a second Incall-enabled app B         (com.beta.B) is downloaded and installed on the device.     -   5. At this point, the android.intent.action.PACKAGE_ADDED intent         is received by A, which fires off a server request with the new         package list [com.magnum.Fighter, com.facebook.Facebook,         com.alpha.A, com.beta.B] to the server.     -   6. At the same time, B is initializing, so it also sends its         package name and the same package list to the server.     -   7. B incorporates a newer version of Incall (we can assume that         the app version is sent along with the package name), so         com.beta.B is higher on the server's priority list than         com.alpha.A.

8. Therefore, the server responds to A telling it to become a slave, and to B telling it to become the master.

In Pseudo-Code:

isMaster = false function onFirstRun( ) {    register_to_receive(“android.intent.action.PACKAGE_ADDED”)    register_to_receive(“android.intent.action.PACKAGE_REPLACED”)    register_to_receive(“android.intent.action.PACKAGE_REMOVED”)    determineMode( ) } function onBoot( ) {    // Do nothing } function onIntentReceived(intent) {    determineMode( ) } function determineMode( ) {    packages = Device.getPackages( )    response = API.call(“packages”, [App.packageName( ), packages])    if (response = = “master”) isMaster = true    isMaster = false }

iv) On-Boot Intent

In this alternative, when the device boots up (or when a new instance is installed), all apps broadcast intents and the system then automatically gives precedence to the latest version of Incall (or some other rule to ensure a consistent precedence between all instances).

Allocation of Revenues

In order to resolve the problem of how to allocate advertising revenues per impression/click-through at each incoming or outgoing call event between n developers when n incall/outcall SDKs are installed on a given handset, the following algorithm is provided.

Incall uses an algorithm which takes as inputs handset and SDK Application (this is an application on a given handset which contains the incall/outcall SDK) end user metrics. Parameters are also defined which assign a weighting to each metric. This weighting and the input metrics are then used to calculate a score for each SDK application on a given handset and then allocate advertising revenue.

The algorithm is continuously optimised to ensure an efficient, fair, and commercially viable distribution of funds across SDK Applications.

An example list of inputs to the algorithm—specifically to allocate revenue—is as follows (assuming that all of the required user/phone identification metadata is available and accounted for):

-   -   Date/time when host app was first installed     -   Date/time when host app was last run     -   Total duration of host app running     -   Frequency of host app launches     -   App category     -   History of ad impressions (and factors associated with those         historic ads, if you choose to store them)     -   History of ad clicks (and factors associated with those historic         ads, if you choose to store them     -   App rating     -   App download numbers (very approximate)

An example weighting output is as follows:

For two Host Apps on a single device, £100 pounds of revenue to allocate

Total Duration of App run time=75% weighting

Total of launches=25% weighting

App A: 10 hours 100 launches

App B: 2 hours 500 launches

Calculation:

App Weight App A B A+ B Duration 0.75 10 2 12 Launches 0.25 100 500 600 B % A % of of A B Weight A + B A + B weighted weighted Duration 0.75 0.83 0.17 0.63 0.13 Launches 0.25 0.17 0.83 0.04 0.21 A B Total Total Duration 62.50 12.50 Launches  4.17 20.83 TOTAL 66.67 33.33

Alternatives & Modifications

App Tokens

In some embodiments, “app tokens” are used instead of “API keys” to allow the association of clicks with (host) apps (of which a developer may have many), rather than clicks for each developer.

Input Metrics

Broadly speaking there are three types of algorithmic inputs (or metrics):

-   -   1. Point-in-time metrics—these are acquired at the time an         incoming call event occurs, and involve the app being brought to         the foreground capturing various data, primarily the incoming         call number, but also other data such as GPS information.     -   2. Long-period metrics—this is collected over longer time         periods. The app may, for example, install a background service         to, say, periodically check GPS coordinates. Alternatively, the         app may use the call log to determine what numbers have been         called or from what numbers calls have been received.     -   3. Personal metrics—this comprises information which is         collected from personal data in the phone itself, such as the         phone directory, or text messages.

The metrics acquired are those which may be used to better select the media content item(s) to present to the user. Some embodiments may however also collect and make use of more esoteric information, such as that acquired from accelerometers.

Examples of Metrics Include:

General

-   -   Current date/time     -   Current phone number on the device (if verified—ideally there         should be an SMS verification process to prove the number is         valid as getting it from the device programmatically may be         unreliable)     -   Device operating system and version     -   Device model and manufacturer     -   IP address(es)

Location Services

-   -   GPS location (current)     -   GPS location traces/history (this may be collected in         background, preferably infrequently so as not to drain the         device battery)

Incoming Call

-   -   Phone number (this can also be cross-referenced against the call         log)     -   Country/region/area of caller (derived from phone number)     -   Whether the number is in the user's contact list or not.

Call Log

-   -   Numbers of callers and callees historically     -   Date, time and duration of calls (also frequency)

Host App Information (the app which is “hosting” the augmentation app)

-   -   Date/time when host app was first installed     -   Date/time when host app was last run     -   Total duration of host app running     -   Frequency of host app launches     -   Any other developer-defined metrics fed out from the host app         (can leave up to developer to decide, for example this could         include app category, etc.)

SDK Information

-   -   History of ad impressions (and potentially factors associated         with those historic ads)     -   History of ad clicks (and potentially factors associated with         those historic ads)     -   Other metrics defined by the system (for example, advertisers         could pay more for a higher “priority” metric)

App distribution system metrics (can be retrieved by scraping the site)

-   -   App rating     -   App download numbers     -   App category

Display Options

When the item of media content is overlaid onto the dialler when an incoming call is received, there are many possible options for how the media content is displayed, including for example one or more combinations of the following:

-   -   only part of the incoming call screen image is overlaid such         that the caller ID can still be viewed and the call can still be         answered and interacted with in the usual manner     -   the entire incoming call screen image is overlaid and call         interaction and ID functions may be provided within the media         content image     -   the item of media content replaces, rather than overlays, the         incoming call screen image     -   the item of media content modifies the incoming call screen         image to enable display of the media content alongside, embedded         in, or in any other way along with the incoming call screen     -   the media content item may be partially transparent, allowing an         animated shape to move across the screen while the rest of the         incoming call screen, the space outside of the animated shape,         remains visible to the user     -   the media content item may be implemented as an overlay as a         floating, resizeable (within limits) view that can be customised         to the user     -   a customised caller ID system is implement as part of the media         content overlay, potentially leaving only the call accept/reject         buttons unchanged

Where it is not possible to have the overlay cover the entire screen (for example, because APIs are prevented from overriding the default call accept/reject actions) the media content item display is implemented as a floating overlay which covers only part of the screen and leaves the call accept/reject buttons exposed.

Media Item Ordering

The items of media content may be sent from the application to be displayed on the screen one by one—in a specified order, or selected at random, or in a combination of random and specific or prioritized order using any algorithms—or multiple items may be sent and displayed on the screen at once.

Audio Media

It is also possible to add a custom ringtone or sound effects to the overlay, which can either supplement the device's ringtone, or replace it entirely. That is, where the item of media content comprises an audio clip such as music, speech or any audio file, which may or may not be accompanied by an image or video clip, the audio clip is played by the loudspeaker in place of the usual ringtone played by the mobile device upon receipt of a call. The ringtone may be intercepted, replaced, overlaid, delayed until after the audio file, or otherwise interrupted.

Cache-Less Devices

In some embodiments there may be no local cache and the phone may remotely download at least one item of media content from the server upon each media content request. It will be appreciated that it may take longer to first download and display an item of media content than it would to display one stored locally.

Outgoing Calls

In another embodiment, media content is displayed when the device user makes an outgoing call to a second party. In this case, the operation is as described above with the exception that the notification sent by the dialler to the application is sent upon occurrence of an outgoing call event rather than an incoming call event, and the image overlaid by the advertisement is the outgoing call screen image and/or presented when the outgoing call is completed, say for a present amount of time.

This functionality may be provided within the same SDK as described in relation to the system for processing incoming calls. In some embodiments, the outgoing call feature may be linked to the incoming call feature; hence the incoming and outgoing call screen images may also be related.

Syncing

The system maintains two separates databases—the main database on the server side, and a smaller database on the phone (cache) which stores a subset of adverts to display to the user.

Periodically, the two caches are “synced” whereby the client purges its cache and acquires fresh media content items from the server.

In some embodiments, the sync time is kept short. This may not be an ideal solution in all circumstances as sync events are not guaranteed e.g. a user may be roaming and have their data connection turned off etc.

Furthermore, because the server-side database can be edited in real-time and the client-side database only fetches those updates periodically, there are cases where the two databases can end up out of sync. For example, if the server has items {A, B, C, D, E, F, G}, the client downloads adverts {B, D, G} into its cache, but then the owner of B logs into the online system and deletes advert B from the system. This is handled in the following possible ways:

-   -   1. B is not fully deleted from the server-side (no items are         ever fully deleted), instead the item is just flagged as         “inactive”. Until the next sync, item B is still shown as usual,         and even clicking on B will take the user to B's website, but         the click is not actually recorded in the database and therefore         the owner of B is not charged, although has free         advertising—while the developer makes no money.     -   2. When B is deleted from the server-side, as before it is         flagged as inactive. When the user clicks the advert, the system         checks if the advert is active. If it is flagged as inactive,         the advert is not loaded and no click is recorded. This also         provides B with free advertising (even though the ad cannot be         clicked, it still appears on the handset).     -   3. As a variant of 2), if an advert is clicked which is found to         be inactive, it is deleted from the cache and not shown again.         This gives B one free click per user, and even though the target         URL is not loaded, B is still getting free impressions.

The situation where an advertiser edits their advert (rather than deleting) is less problematic, but they will need to wait for their edits to propagate through the entire Incall user-base, as there is no way of pushing updates to the users—rather, the update will only take place once the periodic sync takes place.

In some embodiments, rather than have a feature to delete ads from the system, instead each advert just has an expiry time which is part of the advert. Therefore, when the client sync with the server it gets the expiry time of each ad, which means that adverts can expire locally without needing to wait for the next sync (because the phone can always check the advert expiry time against the phone's current time).

Therefore, once an advertiser sets an expiry time for their item, that expiry time is locked and cannot be changed. The clients will then start downloading the ad and the ad will expire at that time. Of course, the expiry time can then be extended (and on the next sync, the expiry will be extended on the client too), but the expiry time cannot be shortened (because we cannot guarantee that there will be a sync event between now and whenever the earlier expiry date is.)

The only vulnerability in this is that technically speaking the user can adjust the time/date on their phone which may result in some anomalous outcomes.

Reporting/Feedback

In some embodiments, the user interaction with the displayed item of media content is reported to a remote server, either in real-time or stored and reported periodically. This feedback may assist in distributing revenue to advertisers and developers.

The system can either be used to track clicks only, or to track clicks and impressions, depending on whether a delayed reporting model, or live reporting is used. The difficulty with tracking impressions is that this data must be stored locally and then transmitted at a later date. Variants track impression data or only clicks.

As shown in FIG. 9, the media content may include two or more buttons, one of which can be used to take up a presented offer and one of which can be used to reject this offer. In this case, the clicks on each button are tracked separately. This feedback may assist in providing user response to offers.

i) Delayed Reporting

In the delayed reporting model (which works well for impressions, and also removes the need for a redirect page), all of the tracking is done locally on the device, and an aggregated report is periodically pushed to the server.

The problem with this approach is that it makes the system more vulnerable to click fraud, and is also more technically challenging to implement.

-   -   The SDK locally stores information about which advertisements         have been served (impressions) and which have been clicked     -   The SDK periodically pushes to the server a JSON-encoded click         report which contains the following information:         -   Authentication information & meta-data about the app and             report (necessary to establish an audit trail)         -   Detailed click report     -   The report is JSON-encoded and pushed to the server API via a         SSL secured connection     -   The authentication information includes the “app ID” (in order         to trace clicks back to their host apps for payment purposes),         along with the “instance ID” (which tracks the clicks for that         specific user)     -   The detailed click report shall consist of the date range for         the current report, and also include a list of each         advertisement and how many times it has been clicked:

Impressions Clicks 10012 4 2 Virgin Atlantic 10048 3 0 Coca Cola 10078 2 0 Nike 10102 8 1 T-Mobile

-   -   An example of a JSON-encoded click report is as follows:

  {  “app_id”:“jMnwWXmmaOqp”,  “instance_id”:“yUXnswIqw”,  “report_id”:7  “report_from”:1355213918,  “report_to”:1355925596,  “metrics”:{   10012:[4,2],   10048:[3,0],   10078:[2,0],   10102:[8,1]  } }

-   -   The click report is sent from the SDK to the server at periodic         intervals, when an internet connection is available     -   Once the click report has been successfully delivered from the         SDK to the server, the local click data is purged and the local         click data store is reset.

ii) Live Reporting

In a live reporting system, when an advert is clicked the user is not sent directly to the advertiser's site, but is first sent to an Incall-controlled redirect page (along with the instance_id to prevent click fraud—or preferable, a one-time code based on the instance_id), where the click is recorded in real-time, and the user is then seamlessly redirected straight on to the advertiser's page.

-   -   1. User clicks advert     -   2. User is taken to redirect page and click is recorded.     -   3. Redirect complete, user is now on advertiser's page

This is a more tried-and-tested approach, and the main advantages of this approach are that it is more difficult (and less effective) to try and commit click fraud on this type of system and also that all click information is available in real-time. It also means that the advertisers can adjust which page their advert links to by editing the redirect on the server rather than having to push out a new set of adverts.

To prevent replay attacks (which could result in click fraud) a one_time_instance_id is preferably used which is generated from the instance_id.

-   -   When an advert is clicked, the SDK shall direct a user to the         appropriate hardcoded redirect site, along with the ad_id and         one_time_instance_id.     -   The redirect page shall then validate the one_time_instance_id         and log the relevant click.     -   The redirect page shall then redirect the user on to the         advertiser's target web page based on the ad_id.

Third-Party App Integration

In some embodiments, the app (and/or SDK) is configured to allow (permitted by contract) third parties to integrate the call-augmentation features within their own app as installed on user devices. Hence, when a call is received by the user device from the company, the app on the user device presents company-specific media content to the user. This may be in the form of a company logo, banner, advertisement and/or ringtone—and presented at the outset, during and/or conclusion of the call.

Post-Call Events

In some embodiments, the app may be adapted to perform certain actions or events after a specific call concludes. For example, after a call from a specific company, a screen may be displayed requesting the user complete a survey based on their experience of the preceding call. This may be provided via another application or via a link to a website hosting the survey.

Use of Temporary Internal Numbers

In an example, companies may assign a new (internally owned) telephone number to a customer for a specific amount of time, this number will, if called or texted, automatically forward all calls or messages to actual customer number. This is useful as it limits the digits that need screening.

Outbound or Augmented IVR

Whereas in a normal IVR system the caller is required to navigate a sometime labyrinthine audio menu system, in some embodiments the app works in tandem with the IVR to augment the caller experience.

The augmented IVR service is triggered when calling a predefined number. This may be done, for example, via the SDK bundled with a third party app installed on the user handset monitoring outbound calls and activating the augmented IVR experience for calls placed to a predefined number or numbers.

An audio menu is activated which explains to the user that there is content on the end users screen Preferably, the app detects whether the device is operating in hands-free mode so as to play the audio via the device loudspeaker(s).

As the caller listens to the audio menu the app presents related options on-screen. These options may be the same as or different to the audio menu options. The caller may for example select from yes/no options eg. “New customer?” or make more specific selections eg. “Sales or technical support?” thereby navigating the IVR menu via the device, for example via a touchscreen.

For a roadside vehicle assistance/recovery embodiment the call may proceed as follows (bold CAPITALS indicate user choice):

-   -   i) New Member or EXISTING MEMBER?     -   ii) Are you calling because you've BROKEN DOWN or is it         something else?     -   iii) Kindly enter you membership number or number plate or are         you a PREMIUM BANK CUSTOMER?     -   iv) Please enter you sort code account number dob and post code         . . . thanks     -   v) Are you in a hazardous place (ie. motorway/main road) or are         you in a SAFE PLACE?     -   vi) are there any children with you Yes or NO?     -   vii) Kindly confirm make and model of car.     -   viii) You are now being connected to the appropriate member of         staff. Your loudspeaker will automatically turn off. Please hold         you handset to your ear.

Other options may for example trigger a call back when an operator is available, allow the caller to request a call back, or to start an online chat.

For the roadside vehicle assistance/recovery embodiment other options may include: arranging a specific time on the call screen for a call back or for handset to automatically self-call to a newly loaded direct-dial number for the appropriate member of staff. In some embodiments the calling or third party could communicate back via online chat on the display or display an on-screen wizard with instructions for the user to perform certain simple vehicle checks.

One advantage of this augmented IVR is that it integrates seamlessly with the user experience via the app, ie. it does not need to be launched separately, say via a company website support forum or during a call from within a website or app. Another advantage is that the IVR menu may be immediately tailored to the specific caller. This may be particularly beneficial to large companies with high volume subscription of the company app.

This IVR functionality may be provided as a stand-alone feature or optionally in combination with any of the example embodiments described herein.

Smart Warm Calling

In some embodiments, the media content item provides information from or relating to the second party in the call to the user. This may allow a second party to identify themselves or provide other relevant information to the user when the second party calls the user, or when the user calls the second party. The second party in this case may, for example, be a bank providing information about customer support services or advising how to contact such services. Alternatively, the second party may be a vendor providing information about their products. Embodiments may be used in conjunction with a telephone conversation about products, providing a way for vendors to “warm call” potential customers, as opposed to traditional cold calling. Preferably, this example may be provided in the case where a user has previously installed an app associated with the vendor on their handset. In this case, the vendor's app may serve as the “host” app for the call augmentation system/software, which may periodically download new information as previously described.

In certain embodiments, the user may interact with the second party in the call via the media content item, or otherwise provide feedback via the media content item. In the case where the call is an incoming call, this is referred to generally as “smart warm calling”.

FIG. 12 shows an overview of a telephone call augmentation system 1000 for “smart warm calling”. This differs from the similar system shown in FIG. 1 in that the media server 30 is in communication with both the client device 10 (to serve media content to device 10) and the second device 150. The media server 30 may be in communication with a plurality of client devices 10, as shown. The second device 150 may be a call-placing device, a telephone or a wider telecoms system, which may be configured to place a large number of calls to a plurality of client devices 10 over a communications network 20. For example, the second device 150 may form part of a call centre.

Along with serving items of media content, the server 30 is also used to supply feedback from the user's interaction with the supplied media content at the client 10 to the second device 150, and also may be used to coordinate the supplied media content with the calls made by the second device 150 to the client device 10.

The hardware used by the client device 10 in the “smart warm calling” system 1000 may be understood by reference to FIGS. 3 and 4, with the difference that the callerID may be supplied via the app 100 rather than the dialler 114, as will be described later on.

FIG. 13 shows an example of “smart warm calling” telephone call augmentation. As shown in FIG. 13, the media content item 101 provided on the incoming call screen is provided with a number of buttons 301 providing hyperlinks to allow the user to indicate that they are unwilling or unable to take an incoming call and to specify a time at which they would like to be called back.

As shown in the figure, the item of media content 101 may further comprise an indicator 302 as to what subject, topic or content the second party plans to talk about during the call. This may comprise text, images, or video, for example, and may additionally comprise audio. Optionally, this audio may replace the device's conventional ringtone. The user, upon receiving a call, is therefore made aware of the subject of the call and thus is more likely to answer it than if he or she receives an unsolicited call, even if they know who is calling. The indicator 302 may also comprise account details in the case where the user is a customer of the calling party, such as account balance, remaining minutes/text/data, delivery time, or date/time of a planned visit (for e.g. meter testing or broadband installation).

In this regard the callerID/name 303 of the second party is preferably presented to the user alongside the item of media content 101, where the callerID/name 303 replaces or appears in addition to the telephone number as would occur normally for contacts in a user's address book. In the case where the second party's name is not listed as a contact in the user's address book, the second party's name may be added to the user's address book. Alternatively, a different indicator of the identity of the second party may be provided in place of their name 303, such as a trademarked logo or sound.

Although the user will be far more likely to answer a “warm call” (when they know who the call is from and what it is about) rather than a “cold call,” they may be unable to pick up the call due to them being busy, or it being an inconvenient time for other reasons. The buttons 301 are provided on the item of media content to enable the user to indicate when they would prefer to be called back. As shown in FIG. 13, a variety of options for different times may be provided. The options defined by the buttons 301 are defined by the provider of the media content. Alternatively, a single button 301 may be provided for the user to indicate that they would like the call to be deferred (for example, showing a message similar to “call me back in 10 minutes”). In some situations, users may be more likely to interact with the item of media content 101 when a single button is provided rather than a plurality of buttons. Optionally, a press of a button 301 may also cause the device to hang up on the incoming call, or may present the user with an option to hang up the call.

Other messages to the second party which may, optionally, be provided by the buttons 303 include:

-   -   Never call me again     -   I prefer to be contacted via text/email     -   I never want to be called at this time     -   Call me back in the morning/evening     -   I am not interested in talking to you about [this specified         subject]     -   I would be interested if you are calling about/will call back         about [another subject]. (i.e. a ‘menu of options’, as will be         described in more detail later on.)

The buttons 301 may also provide a number of ‘quick responses’ to the subject of the call, as indicated by the indicator 302, so that the user can quickly reply to the calling party if they are unwilling or unable to discuss the subject in a phone call. For example, if the user has made an appointment with a doctor (or other specialist) via a centralised app, the doctor may call the user if they need to reschedule the appointment. This is indicated to the user by the indicator 302, and the user may be provided with a number of alternative appointment times (which could be informed by the content of the user's calendar app, provided that the user has previously indicated that the app may access the native calendar app on the device) via the buttons 301. If the user does not want to take any of the suggested appointments or wishes to discuss the matter in detail, they can simply answer the phone and rearrange the appointment during the call.

The second party may then call the user back at the specified time, contact the user via another communication channel (such as email), or simply log the data in order to build up a model of when all users or the specific user prefers to be called and/or the topics of specific interest to them. Alternatively or additionally, when a button 301 is pressed, calls from the second party may be blocked for the specified time period, ensuring that the user does not receive a call from the second party during this time period. Alternatively, the system 1000 may be arranged to cause the user's device to place a call to the second party at the specified time. In this case, the user may be alerted that this call will imminently take place by a tone or other notification, and may be provided with a further item of media content 101 on the outgoing call screen with which they may interact to further defer the call, select an exact time at which they wish to be called back, or select another option.

This system 1000 is particularly useful for companies offering special offers via telephone, as in the example shown in FIG. 13.

This system 1000 could also be applied to personal calls, or any other type of telephone call where the calling party is known to the user, for example, but not exclusively, when the calling party is not listed as a contact in the user's address book. In some embodiments, the calling party may provide information, such as an indication of the subject of the call, by way of text or an image (for example an emoticon), ahead of the call thereby allowing the callee an opportunity to decide whether or not to take the call—or indeed to have a moment to prepare for the call.

FIG. 14 shows another example of “smart warm calling” telephone call augmentation, in which the user is provided with a survey 304 or other list of options.

In this example, the media content item 101 provides a means to engage with users, which may make them more likely to accept the call. The option chosen is reported to the second party as previously described, and may feed into the content of the subsequent call—for example, the survey 304 may ask the user which model of phone they would like in their upgrade, which might then be discussed in the call with a sales representative. This survey 304 might also be used for market research, allowing the user to provide feedback about the level of service they receive, for example. The survey 304 may be presented alongside the indicator 302 of the subject of the call or without this indicator 302, depending on use. Where no indicator 302 is provided, this function may be used to provide the user with a menu of options of what is to be discussed during the call, in which case the option selected may be used to assist with connecting the user to an appropriate sales representative or branch of an IVR (interactive voice response), for example. This menu of options may alternatively be provided by a third party. The survey 304 may alternatively be part of an ongoing advertising campaign, or similar, and is provided to raise awareness.

An alternative function of this telephone call augmentation may be used to generate inbound calls to relevant sections of a call centre, where a button press causes the current call to end and a new call to be placed from the user's device to the call centre. In this case, the sole purpose of the incoming “smart warm call” is to encourage the user to press a button and thereby make an inbound call back to the call centre.

User interaction with a button 301 on an item of media content 101 may cause a second item of media content 101 to be shown, which may provide a further menu of options. This may be useful for allowing a user to provide further detail about their instructions or preference. For example, if the user indicates their favourite model of phone in response to a survey 304 provided as an item of media content 101, the second item of media content 101 may be used to allow the user to pick a reason why they prefer that model of phone.

The item of media content 101 may also provide a button 301 giving the user the option to ‘live chat’ rather than take the call. User selection of this button may cause the incoming call to be cancelled or hung up and trigger the launch of a realtime online chat window or program, allowing the user to converse with the caller or a representative of the caller. The chat window or program may be accessed via an external application or may be built in to the application providing the “smart warm calling” functionality. The chat window or program may provide the ability to add new users into the conversation and allows files to be transmitted bi-directionally.

The item of media content 101 may also provide a button 301 giving the user the option to convert the call into a Voice over IP (VoIP) call. User selection of this button may cause the call to be cancelled or hung up and may automatically trigger a call-back via a VoIP service, such as Skype or Viber. Alternatively, the user's device may place the call out to the original second party, where the second party's VoIP contact details are provided with or associated with the item of media content 101.

It will be appreciated that the features of the system 1000 shown in FIGS. 13 and 14 may be combined, and that further features according to other examples as shown in FIGS. 6-9 or as described above may be incorporated into the “smart warm calling” interface shown in FIGS. 13 and 14. It will also be appreciated that the features of the system 1000 shown in FIGS. 13 and 14 may be used in the previously described example of the system 1 as shown in FIGS. 6-9, with the user being able to provide feedback to the third party providing the media content (or initiate a chat session or convert the call to a VoIP call, as described).

It will be appreciated that the buttons 301 provided on the item of media content 101 as input means may be replaced or used alongside a variety of alternative input means, which may include the detected orientation of the device (where turning the device face-down means ‘call me back in an hour’, for example), a detected gesture made by the user, an audio command, shaking the device, a drawn pattern or swipe on the screen, or a signal from an auxiliary device configured to communicate with the device. In particular, the user may manipulate a dial or clock hands displayed on the device or on an auxiliary device to specify the time at which they would like to be called back. The item of media content 101 may also comprise a slider allowing the user to quickly and precisely communicate a quantity, rather than picking from a number of discrete options provided by buttons. This may be particularly useful where the user is asked to specify a call-back time or is asked how much they would be willing to pay for an item as part of a survey, for example. The slider may extend from a minimum of 5 minutes to a maximum of 24 hours, for example, when the relevant quantity is time.

The ‘clicks’ or user selections of each button 301 are tracked and reported separately as previously described. ‘Clicks’ may be recorded and subsequently sent to the second party. The item of media content 101 may indicate to a user that a button has been pressed, such as by highlighting the button. An interaction with a button may also prompt the user to be shown a message, which may be a simple confirmation that their engagement has been noted or may encourage them to answer the call, for example.

When a button 301 is pressed, the second party may be alerted as to the option chosen by a number of possible means, such as a text message, an email, or by sending a signal over a data connection to a server operated by the second party and identified by a URI associated with the button 301. Preferably, live reporting (as described above) is used, so that user feedback can be integrated into the subsequent phone call (for the case when a user provides feedback and then answers the call).

Preferably, the display of an item of media content 101 causes an indication to be produced, which is then reported to the second party at a later date, such as when new items of media content 101 are downloaded. Alternatively, this may be reported live, as previously described. This indication may be associated with the item of media content 101 and stored in the cache, for example, until such time that it is reported. The purpose of this indication is to prove to the second party that the desired item of media content 100 was indeed shown to the user on the call screen for the relevant call.

As previously mentioned, the user may also choose to receive “smart warm calls” rather than accept advertising within an app. These calls may be from third parties with some access to the user's data, either via the app or via alternative means.

Implementation

For “smart warm calling”, the app used as part of the system 1000 is configured to recognise ‘qualifying phone numbers’ that are saved onto the device's memory. An index of these ‘qualifying phone numbers’ may be downloaded to the device when new items of media content 101 are downloaded to the device 10. Alternatively, this index may be downloaded to the device periodically or in response to a forthcoming call event. Optionally, these qualifying phone numbers may be provided via a separately downloaded piece of software. Media content items 101 are downloaded to the device prior to the call. The items of media content 101 according to the examples shown in FIGS. 13 and 14 may be stored in a cache, as previously described, and displayed when an incoming call from a qualifying number is detected by the app (which may run as a background service, as previously described).

The second party may be able to control when new media and rules for display are pushed to user devices 10 and when they are removed. The app on the device 10 is configured to check the server 30 to see if any new items of media content 101 should be downloaded and to see if any should be removed every time the server is accessed. This may occur every time a user accesses and/or logs in to the app used as part of the system 1000. For example, for a banking app, new items of media content 101 may be downloaded every time the user checks their balance. As described above, in some embodiments, the mobile device 10 may also periodically access the remote server 30 and download updated media content. The frequency of accesses the sever 30 by the device 10 can be changed by the provider of the app, and may also change subject to other actions.

Each item of media content 101 may be flagged with an “expiry date” as previously mentioned. This is especially relevant to items of media content associated with a limited-time promotion, which are then removed when the promotion expires.

FIG. 15 shows an example implementation in flowchart form of an application according to the present invention used for “smart warm calling”.

-   -   S1. When an incoming call is detected, an incoming call event is         triggered by the operating system and the dialler sends         notification of the incoming call event to the application 100.     -   S2. The phone number is checked against the list of qualifying         phone numbers—if it matches, the application 100 seeks to         display an item of media content 100. If not, the application         100 takes no further action. Another instance of Incall may take         over at this point.     -   S3. The application 100 looks up the item of media content 101         to be displayed. This is preferably predetermined, as will be         described later on.         -   This may involve the application sending a media content             request 102 to the cache. Upon receipt of the media content             request the cache sends the media content item 101 to the             application 100.     -   S4. The item of media content 101 is displayed on the call         screen.     -   S5. The user may interact with the item of media content 101 as         described above.     -   S6. If an interaction is detected, information related to this         interaction is recorded and is transmitted to the second party.     -   S7. The user may interact with the item of media content 101         while the phone is ringing, that is, up until such time that the         call is accepted, rejected, or times out     -   S8. The item of media content is hidden at this point.     -   S9. The app may then terminate itself. Alternatively, the app         may remain in the background for the duration of the call and         then perform an action (such as reporting feedback or opening a         hyperlink) following the termination to the call, as previously         described with reference to FIG. 5.

The media content items 101 downloaded by the device from the server 30 may be based on a profile of the user, which may be informed by prior feedback provided by the user interacting with the media content items 101. The information included in his profile may also comprise network operator/tariff, device model, other apps on device, call frequency/text frequency/data usage, volume of changes of location, battery size, and number of contacts, among many other options.

Where a cache 112 is used, the media content items 101 in the cache 112 may be updated as described above. However, for large download file sizes, such as where many complex media content items 101 are downloaded, the download of the media content items 101 may be integrated into an update of the app used as part of the system 1000. Where the user's permission is required to update the app, this could be requested via a button provided on an item of media content 101 in a “smart warm call”.

Multiple Instances

In an example, where an app providing the “smart warm calling” functionality is provided this app will always take precedence such that the item of media content associated with the “smart warm call” will always be displayed on the call screen in place of an item of media content supplied by another app. This can be implemented in a number of ways, such as by putting the phone number(s) associated with a smart warm call on a whitelist associated with the other apps, checking to see if the app providing “smart warm calling” responds to a call before launching other apps, or by making the app providing “smart warm calling” the ‘master’ according to any of the models listed above with reference to providing support for multiple parties.

Where multiple instances of “smart warm calling” are present on a device, the incoming phone number will be checked against all open instances of client applications using smart warm calling in order of ‘last time application used’, before then reverting to Incall applications without “smart warm calling” functionality, if provided. As soon as a phone number is recognised by a client application using “smart warm calling,” a media content item 101 is displayed and the number is not searched against additional instances of the software used as part of the system 1000 provided on different apps.

External Sync

The item of media content displayed when an incoming call is detected may be chosen according to the algorithms described above, but in many situations it is advantageous that the item of media content 101 to be displayed is coordinated with the planned content of the incoming call, so as to maximise the relevance and usefulness of the item of media content 101 and to provide a more integrated user experience.

FIG. 16 shows an example method of coordinating the content of the phone call and the item of media content to be displayed. In this method, the media content items are downloaded into the cache with an associated identifier (S1), the identifier being a property of the call. This property is preferably the suffix to a qualifying phone number. This association may be made at an optional ‘priming’ stage (not shown) or may be provided together with the media content item as part of the index of qualifying phone numbers. When a call is detected (S2), the app compares the relevant property of the call against the media content item identifiers (S3) and identifies the appropriate media content item (S4). This media content item is then shown on the call screen (S5). This method is preferred because it allows the item of media content to be effectively and simply coordinated with the planned content of the phone call, but requires a relatively high level of telecoms infrastructure.

Optionally, an exchange of information takes place prior to a “warm call” being placed. This ‘priming’ stage occurs before S1 shown in the flowchart of FIG. 15, and provides an alternative means of specifying the item of media content to be shown, so that the item of media content 101 matches the planned content of the phone call. This priming information may be delivered to the device 10 from the second party in a variety of media, although it is advantageous that the user is not made aware of this priming stage taking place. The information may be delivered via a GSM mobile network or via a data connection, for example, and may comprise a signal indicating the item of media content 101 to be shown next out of a plurality of items of media content 101 available for selection from the cache or a schedule of items of media content 101 to be shown alongside the next specified number of phone calls. This schedule may be updated or revised in response to data gathered about the user and/or user feedback, indicated via the user's (or a number of users') interactions with items of media content 101. Optionally, this signal may further comprise instructions related to which item of media content 101 should next be downloaded to the cache, or may comprise an item of media content 101 which is downloaded into the cache.

FIG. 17 shows another example method of coordinating the content of the phone call and the item of media content 101 to be displayed. In this example, media content items 101 are downloaded with an associated place in a schedule (S1). A ‘priming’ signal may be sent from the second party to change this order by providing a new schedule (S2). When a call is made (S3), the first item of media content 101 in the schedule is displayed (S4).

FIG. 18 shows another example method of coordinating the content of the phone call and the item of media content 101 to be displayed. After media content items have been downloaded into the cache at an earlier time (S1), the app used as part of the system 1000 of the present invention may send a signal (S3) indicating what (if any) items of media content 101 are available in the cache in response to a request signal from the second party or the server (S2). This request signal may be provided as part of the priming stage, or may take place subsequently. The signal from the second party requesting information about cache content may relate to a specific item of media content 101, thereby functioning as a ‘check’ that the smart warm call will be successful, in that the correct item of media content 101 will appear. Optionally, a further ‘priming’ signal may be sent from the second party to the app (S4) to specify the media content item to be shown, as described above. Following these steps, the call is made (S5), the app looks up the media content item 101 to be displayed (S6) (based on the priming signal, a schedule, or an identifier) and the media content item is displayed (S7).

Alternatively or additionally, the second party may keep a record (for example, in a database) of what items of media content 101 are available in the cache from records of previous downloads. Alternatively, the item of media content 101 may be chosen at random from a plurality of media content items in the cache, or only one item of media content 101 is available in the cache at any given time. In this case, the use of a priming stage is not necessary. As previously described, the section of the item of media content 101 to be displayed may be informed by the time of day or user location, among other factors.

FIG. 19 shows another example method of coordinating the content of the phone call and the item of media content to be displayed. This method provides a method for a new item of media content to be sent to the device immediately prior to the call. In this example implementation, the calling party may send a ‘priming’ signal indicating that a call will shortly take place and that the relevant item of media content should be downloaded (S1). The device may then test to see if it is connected to Wi-Fi (S2). If the device is connected to Wi-Fi, it will connect with the server and download the relevant item of media content (S4). The completion of the download is signalled to the server (S5), indicating that the device is ready to receive a call and display the correct item of media content. Where the device is not connected to Wi-Fi, the device may wait for a predetermined time period and then test again (S3). This may result in a long delay between the ‘priming’ signal and the download of the media content item, so an additional step is included in which the server tests to see if this is likely to be a suitable time by referring to factors including the time of day, the device location, and data of the user's previous interactions with the system (S6). If the server determines that the user is likely to not take the call, the call may be deferred and the system may wait for a defined time period before testing again (S7). Alternatively, a call may be scheduled for a time when the user is likely to be free and willing to take the call. When the call is made (S8), the newly downloaded item of media content is shown on the call screen (S9).

Alternatively, a mobile data network may be used to download the media content item. Optionally, where no Wi-Fi connection is available, a media content item 101 from the cache may be displayed instead—in this implementation, it may be beneficial for the media content items 101 in the cache to be applicable to a wide variety of situations, while those downloaded immediately prior to a call (if possible) are specifically related to the subsequent call.

As an alternative, the item of media content 101 may be sent at the same time as the phone call. In this case, the same communication channel is preferably used for both purposes. This is most useful for voice-over-IP calls, where there is more likely to be sufficient bandwidth available, and provides the advantage of added flexibility about which item of media content 101 is shown.

It will be appreciated by the skilled person that there are many potential ways in which the planned content of the call and the item of media content 101 could be coordinated, and elements of the examples listed above may be combined.

Other Implementations

The skilled person will appreciate that aspects of the invention may be implemented in alternative ways in accordance with the specific hardware and software capabilities and restrictions.

FIG. 20 shows another example a telephone call augmentation related to smart warm-calling, in this example on an iPhone running iOS.

As with the Android implementation described previously, the user downloads the SDK as part of—or in addition to—the third-party app. However, whereas Android permits greater control by third parties of the incoming call screen (as mentioned previously, in the case of OEMs allowing its replacement entirely), this facility is restricted in iOS. Consequently, for iOS devices the corresponding SDK makes use of the native ‘contacts’ facility, loading suitable third-party contact information including one or more telephone numbers and a display profile into the contacts or address book database, so that when the calling or third party calls the user from a recognised number the caller display screen displays the calling or third party information, much as it would for a regular contact.

The third-party contacts information may be pre-loaded in advance of the call or in some embodiments the information is provided and the contacts updated in real-time. FIG. 21 shows call screen user notification by way of a) a basic (push) notification and b) an interactive notification.

A back end system is configured to send the user or callee a personal (sniped) ‘interactive push notification’, preferably timed to appear on the call screen at the same time as the incoming call. This may be a basic (push) notification or an interactive notification allowing the user to respond directly without taking the call.

The item of media content displayed to the user may therefore effectively comprise contact information in combination with a (push) notification.

Timing the push notification to sync or coincide with the incoming call is done by making use of the phone internal diagnostics and/or the network signal so as to mitigate for signal and/or hardware delays. This may be done by having the app on the user device report to the calling or third party that it is in a good signal reception area and has app notifications activated. Alternatively, this information may be obtained in response to the device being polled by the calling or third party in advance of a potential smart-warm call.

In some embodiments, the app also determines whether the user is likely to be poised to receive a call—which is discussed in more detail below.

FIG. 22 shows a call screen with an SMS response facility.

In some embodiments, the user response may be prompted via SMS rather than via interaction with an interactive notification.

The implementation described above may also be applied to embodiments such as:

-   -   Call screen display/advertising (as previously described with         reference to FIG. 5, suitably adapted)—wherein content is synced         in real-time to existing contacts for which no profile picture         is stored for display when an incoming call is received from one         of said contacts. Such facility may be used by network operators         and/or mobile virtual network operators (MVNOs)—or indeed for         any app. In some embodiments, each interaction with the         displayed content eg. a ‘clickthrough’ or social media ‘share’         would earn the user points or prizes.     -   ‘Perfonality’ of the person-person app interaction, allowing a         user to communicate a message, for example as a notification,         say a push notification, in parallel with placing a call,         preferably relating to the reason for calling eg. as ‘2 mins . .         . it's about sunday’. Person-to-person smart warm calling is         also discussed in more detail below.

Alternatives

As mentioned above, the “smart warm calling system” may, optionally, be extended to apply to personal calls, as in ‘person-to-person smart warm calling’, in which case both the devices used by the caller and the callee must have the same app installed, or alternatively two separate apps which are arranged to communicate. In this example of the system 1000, the app used as part of the system 1000 (or a separate app) may be provided with the functionality for a caller to select the options that they wish to present to the callee via buttons or alternative input means, as previously described. These options may be selected from a list, or there may be an option for the caller to write or customise their own buttons. Alternatively, a default set of options and/or item of media content may be provided. The option selected by the callee may be presented to the caller using the caller's app. The functionality may also extend to allowing the caller to change the way their picture, contact details, or even phone number appears on the callee's call screen by replacing (or hiding) these elements with an item of media content. The font used and positioning of elements may also be specified. The item of media content 101 shown to the user on the call screen is therefore preferably totally customisable by the caller. In addition, the ringtone heard by the callee when the caller calls may be specified by the caller.

The caller may customise the item of media content 101 to be shown (and the ringtone to be heard) by editing a ‘caller profile’ via the app on their device. The caller may specify a plurality of caller profiles to be used for different callees, so as to provide items of media content and ringtones that are appropriate to different callees. The callee may be able to preview the item of media content to be shown for certain or all contacts via the app, and block items of media content or certain elements of items of media content. As such, users of the app may be notified when contacts update their caller profiles, so that they are provided with the opportunity to preview the item of media content.

Buttons 301 providing the callee with the option to open a chat window, share content on a social network, or convert the call to a VoIP call may be particularly useful in combination with this example implementation of the system.

The use of the system with personal calls is particularly useful with the advent of ‘personal branding’ as a product of social/professional online networks, and provides for users to brand their contacts' call screens.

Optionally, an item of media content 101 as described in relation to “smart warm calling” may be presented to the user on a call screen of an outgoing call. This call may be to the party providing the items of media content and/or the app, for example, or may be to an unrelated party. This functionality is particularly useful where inbound calls are generated via a previous interaction with an item of media content 101, as described above.

Optionally, a further item of media content 101 may be presented to the user as described following the termination of any accepted call from the second party. This item of media content 101 may, for example, request that the user provide feedback about the customer service they received during the call via a list of options, as described. Optionally, the app may therefore remain in the background as the call takes place, and only terminate itself following the display of the described further item of media content 101.

Optionally, an item of media content 101 may be presented to the user mid-call to provide additional functionality to a phone call. For example, the calling party may ask the user to turn on speakerphone and look at the call screen, where an item of media content 101 may be displayed providing buttons allowing the user to interact with the item of media content 101. Alternatively, the item of media content 101 may show an image or video for tutorial purposes, a secure password, or a live video or text feed, for example. The item of media content may also present the user with the option to share content on social media, open a chat window, or complete a survey as previously described.

Optionally, an item of media content 101 may be presented to the user on a call waiting screen, which may appear when the user receives a call from the party providing the app when already engaged in a phone call. This is particularly advantageous as the user can indicate their call-back preferences rather discontinuing their existing call, which they may be unwilling to do.

Optionally, the app may access the native device hardware technologies—such as the smartphone accelerator, eyeball trackers and/or camera(s)—to determine device and/or user data.

This data may be used to notify a calling or third party (in response to a query made of the device) that the end user is amenable or poised to receive a phone call. For example, eye tracking and/or accelerator data may be used to determine whether a user is using their phone for games or browsing.

In some embodiments even without accelerator and/or eye-tracking data it is possible to determine whether the end user is poised for call, for example by noting contextual information such as they have just finished texting someone.

In some embodiments, the user may set preferred times for when they would be willing to accept a call or excluded times when they would not be so willing.

In some embodiments therefore a determination is made whether and when to place a smart-warm call to a user in dependence on one or more of: signal strength at the device, configuration of the device, amenability of the user and user preference.

Device and/or user data may be used to track whether the customer/user has seen and their reaction to—and optionally determine whether they benefited from—smart warm calling. This will have implications on conversion data and also on the fees charged to calling or third parties.

In some embodiments, calling or third parties may be offered the option to ‘piggy back’ and provide smart warm-calling via the app of another (calling or other) party. This relies on some call screens being stored natively and some numbers being added for the SDK to screen.

It will be appreciated that these alternatives and modifications, while being complementary to the “smart warm calling” example of the system 1000, may also be used together with the previously described examples of the system 1 to provide additional functionality.
